SETS

Boxed sets were available throughout the production of the Wrenn Formula 152 system from September 1960 through to their demise, probably during 1968*. From the outset the first set introduced was Set No 1 and this remained the only set available until a batch of sets then appeared after August the following year. It was named as the ‘Basic Set’ probably because it only contained cars, controllers and track with no fencing or posts included. Other sets quickly followed and were featured within the Catalogue and Price Lists through to the last special sets that were advertised in the modelling press in January 1967. All of the later sets included a Deflector Straight and when the next generation of set boxes were introduced later in 1963 the ‘Basic Set’ title was removed in the Price Lists and the new No 1 set then included one of the Deflector straights. Finally the 9-volt sets were launched probably at the latter end of 1967 running through into 1968*, although the exact dates for these cannot be confirmed, however these simple sets reverted to a very simple number of contents as itemised below.

Most of the sets were available with two cars whilst some later sets contained three cars and these were denoted with an ‘A’ suffix. Included in each of the sets was a sealed small square Blue paper bag which contained ‘Spare Current Collectors and Fixing Screws in Case of Loss or Damage’. All of the sets included a Cream guarantee card with Green printing featuring a perforated return section (similar to a postcard) for registering the ownership of the set with the manufacturers. The highest number seen on the Sets guarantee card is B 32646 and for the cars 34125, are any higher numbers in existence?

Two Extension Packs became available between August 1961 & July 1962 which included a number of Track sections, Bridge Supports, Fencing & Fence Posts. One of these included an additional Car and a Controller as well as the other items listed above. The 9-Volt set was produced late in 1967 and this is generally considered to have been the last set available.

The first generation of set boxes were constructed from strawboard with a printed paper overlay which was stuck to the lid with adhesive and a box base covered in a Dark Red gummed paper. The paper overlay to the box lid was printed in Yellow, Red, Green & Black featuring a Black & White overprinted photograph of a Grand Prix on the box lid face and sides. The box lid featured the words ‘Wrenn Formula 152’ over an illustration of a plan of an oval track layout including the words ‘Triple Electric Model Motor Racing’ and ‘Made in England by G. & R. Wrenn Ltd., Basildon,. Whilst the size of the box lid was standard at 17½” x 10⅝” x 2¼”, the box base was available in two different depths of 2¼” or 2¾”, the extra half inch enabling more track to be included in the box to accommodate the larger sets.

When the 2nd generation of set boxes were introduced during 1963, Wrenn were still manufacturing the AC Vibrator-motored cars but this change was probably prompted by the introduction of the new Set No 0. This time Wrenn decided to accommodate the different sized sets with manufacturing one size of box in two different heights, with the bases and lids being the same size. The boxes were 18½” x 14″ with heights of 1″ or 2¼” and were both constructed from folded White cardboard, with the lids having full colour printing to the top and sides. This design used an illustration to the top which included the original one of the Cooper, this time with two of them together with a new illustration of a Maserati. The rest of the lid design included graphic areas printed in similar colours to the previous generation lids, again with the text included. The same method of identifying the different set contents was also used as previous and when Wrenn introduced the new DC motored cars they just changed the text which featured in the bottom left hand corner to highlight this change.
