The terminology of each of the following packaging items has been taken from Wrenn’s standard Order Form. Wrenn only referred to ‘boxes’ when itemising the cardboard Set containers or those for the Transformers, all of the other cardboard containers were referred to as ‘cartons’ whilst the bagged Accessories and Spares were available in ‘packets’.

The 1st generation of set boxes had a standard size of 17½” x 10⅝” x 2¼” for the box lids, and the corresponding box bases were available in two different depths of 2¼” or 2¾”. The box inners were composed of Pale Blue-faced strawboard main dividing sections with Yellow-faced strawboard and paper sections for the Track areas. One of the set box lid ends had a White rectangle left out of the Red printing so that the particular number of the set could be overprinted. The Set No 1 ‘Basic Set’ box was peculiar in having a single, central piece of Pale Blue faced cardboard with ‘H’ shaped cut-outs for the two Cars and rectangular cut-outs for the two Controllers and the Bottle of Oil. The later box layouts were then modified to provide enough space for the additional track pieces with the deeper box bottoms and different depths of track packing pieces. The Cars and Controllers were fitted into small individual Pale Blue coloured cardboard trays. There were six of these provided so that they could accommodate either the two Cars and Controllers for the later Set No 1, Sets No 2 & No 3 or the larger sets with the three Cars and three Controllers in Sets No 2A or 3A. When the smaller sets contained only two Cars, the spare trays for the ‘absent’ Car and Controller had the small Pale Blue boxes simply turned over. A single example of a 1st generation set box has been seen with the interim self-adhesive paper sticker (as described below). Since this is extremely rare to be seen on a 1st generation set box it is assumed that a dealer was just using up an old stock box.

Wrenn latterly replaced the central Yellow cardboard support for the Cars, Controllers & the Bottle of Oil, which had proved to be quite vulnerable to damage, with a vacuum-formed Pale Yellow polystyrene tray. This had rectangular recesses for these items and also included a raised ‘152’ with an outer raised ring. All of the items were a ‘snug’ fit into these recesses which successfully retained them when the box was being moved about and was also the predecessor of the complete vacuum-formed trays which the later 2nd generation boxes used.


The next generation of set boxes were all larger in plan, being 18¾” x 14” x 2¼”, but the new Set No 0 box was the exception being only 1” deep. They were constructed from White cardboard for both the lid and base with the box lid again being printed in predominantly Yellow with Red, Green & Black but this time it was an illustration of two Coopers and a Maserati racing cars. In the bottom left hand corner there was a Black rectangle which contained the words ‘Three Cars On Each Lane’ and on the opposite side there was also included the following words in Red ‘Exciting lane changing for overtaking Grand Prix circuits at table top size’. When the DC-motored cars were introduced the set box lids were upgraded to advertise this and the Black text box then included the words ‘New’ in Red within a White flash, and ‘Super DC Rotary Motor, 3 cars in each lane’ in Yellow. A minor additional point is that these new set box lids also had the Red text lowered slightly. As an interim measure, during the introduction of the DC motors, Wrenn had a number of Green & Black printed self-adhesive paper stickers made available to the dealers. These were to enable them to update their existing set box lids to advertise the new motors, if they wished, to upgrade any of their existing AC stock of sets with DC Cars and Controllers. The words ‘New Super DC Rotary Motor’ were included on the stickers and only a few of these seem to have survived over the years. All of the set inner trays were vacuum-formed in a Pale Yellow polystyrene but a few Set No 0 inner trays were also produced in White. There were only three variants of these vacuum–formed trays with different arrangements of the individual components to accommodate all of the range of 6No sets.

Extension Pack boxes were constructed in the same way as the current (1st generation) set boxes although they were smaller, being 10⅝” x 8⅛” x 1½”. They featured the standard Wrenn illustration of a Cooper in the centre of the lid and were printed predominantly in Yellow with Black, Red & Green, they included the round Wrenn logo with the words ‘Wrenn Formula 152’ and just the large Red words ‘Extension Pack’. One of the box lid ends had a White rectangle left out of the Yellow printing so that the particular number of the Extension Pack could be overprinted and the box base was again being covered with the Dark Red gummed paper. These sets also contained a piece of folded card printed in Red with Black lettering and a Wrenn Formula 152 badge which retained some of the pieces.

The three Special Sets that were advertised in January 1967 were each promoted to include a special presentation box. As yet, there is not any recorded information on these boxes although they must have been quite large in comparison to the previous set boxes since they contained a larger number of components with the largest set even including a transformer.

The final 9-Volt set box was the same size as the previous Set 0 box but this time featuring a full-colour illustration of the Vanwall and Maserati cars racing on the lid. It also included the following marketing text ‘SUPER Battery powered Slot racing Set, Two Precision built Mini-Scale Racers, Racing-style Push-start New type Motors, Engineered for Extended Battery Life, SPEED & BRAKING Hand Controllers, Complete with Crash Barriers & Pylons’. A further statement was quoted ‘Requires two 4½ Volt Ever Ready 126 batteries or equivalent’ and this box was unusual in that it did not have Wrenn’s name emblazoned over it. Instead the only reference to Wrenn was in very small letters in the bottom corner under the text ‘Made in England’ stating the company’s name and address, almost as an afterthought. The various items contained in the box were retained in the same vacuum-formed plastic inner tray as seen previously in the Set No 0 box.

Each of the Power Units were supplied in a manilla-coloured, corrugated cardboard box, 5″ x 4 3/4″ x 3″. These were fabricated from two rectangular pieces of corrugated cardboard which were folded and then stapled together. The box was completed with a printed Blue and White gummed self-adhesive label with the Power Unit type and specification on the outside together with a guarantee card.

Individual cars were supplied in printed cardboard cartons that also contained a Pale Green paper instruction sheet. The first car cartons were peculiar to the specific car they contained with either an illustration of a Ferrari or a Cooper printed on both sides of the carton. The Ferrari carton featured printing in Red & Black whilst the Cooper’s was in Green & Black. As the Yellow Ferraris and Blue Coopers were introduced their cartons then included a small self-adhesive coloured paper dot stuck to the end flap of the carton in order to denote the colour of the car inside. As different types of cars were introduced Wrenn decided to use a standard, generic type of carton. This design was produced with a graphic patterned display of solid colours and stripes in Red & Black on one side and featured the original Ferrari illustration on the other. This new design had Black end flaps with a White elliptical area left for the printing of the car’s name, it’s colour and type number on one flap. When the DC-motored cars were introduced the same carton was utilised but the elliptical area on the flap was also overprinted in Red with large ’DC’ letters. Initially some of these cartons featured a White gummed paper notice stuck to the bottom outer side of the carton, reminding the buyer that the car inside was actually ‘DC-powered’ in Red. All of the individual car cartons also included a Pale Green paper guarantee with Black printing and a perforated return section for registering the ownership of the car with the manufacturers.

The Trackside Pit building kit was supplied in a cardboard carton with Mid-Blue & Black printing on the outside of the carton titled ‘Trackside Pit – with space for two cars’. The carton illustration included both standard versions of the Trackside Pit buildings with the ‘Cooper/Ferrari’ and ‘Vanwall/Maserati’ versions of the pit name boards in a row with a Grandstand further down the line.

The Grandstand kit was supplied in a cardboard carton which was obviously larger than the Trackside Pit carton and was printed on the outside in Red & Black, it featured an illustration of the Grandstand in the foreground followed by a row of Trackside Pit buildings behind.

The 2No different pre-painted figure sets were available in cardboard cartons with a cellophane front section so that the contents could be viewed. The White-faced cardboard had Green and Black printing to the outside and was produced for either set with tick boxes printed on one of the end flaps to indicate which set was contained within. The figures were held in place in a folded cardboard insert which was printed with a Pale Green display having a view of a racing circuit. There were two different inserts produced which were necessary to accommodate the different standing/seated figures within each of the figure sets.

Various items of Track were available separately as well as in the sets. These were supplied in cardboard cartons that were printed in Mid-Blue & Black in the standard graphic display of blocks of colours and stripes. Some items were available singly such as the Deflector Straight, the Lap Counter and the Chicane Set and these also contained the relevant Pale Green instruction sheets. The other standard items of Track such as the Straights, 4” radius Curves, 8” radius Curves and the 12” radius Curves were only supplied in cartons containing twelve pieces of Track. It seems from the standard Order Forms that the Terminal Straight was only supplied singly and not in a carton.

The Bridge Support Set was supplied in a cardboard carton 4″ x 3 1/16″ x 1 5/16  which was printed in Yellow & Black and depicted an illustration of the items and their use. This carton also contained a Pale Green instruction leaflet describing how the Bridge Supports should be used.

The carton for the controllers were specific to the item, they were printed in Red & Black with the graphic patterned display of solid colours and stripes and they were the same size as the cartons for the Cars. The initial E1 Controller cartons featured the standard graphic display in the centre section and the end flaps were printed alternately Red and Black with the lettering ‘CONTROLLER’ together with the Wrenn name and address in the contrasting colour. The later Mk 2 Controller cartons reverted to using the generic design with one side as previously used for the Ferrari and one of the end flaps was printed in Black similar to the later Car Cartons leaving the central White ellipse featuring Black text stating ‘CONTROLLER VARIABLE Type E.1.DC’.
