A number of display layouts were built by the factory to promote Wrenn Formula 152 at exhibitions and toy fairs. They were built to be totally functional and included items from the existing range of buildings and accessories. At the time of the 1962 Brighton Toy Fair, Wrenn did announce to the trade that there were smaller display layouts available for dealers to use in their toy and model shops or even as a static display in their windows. It now seems that there were at least seven different display layouts built which made appearances at exhibitions and photos of them were used in Wrenn’s 152 Catalogues, in adverts and also in books. Unfortunately there are only single, partial view photos available of two of these layouts and no further details. So even though they did include the Wrenn railway track the whole layouts can only be imagined at this time.

The simplest display layout seen was an oval of track mounted onto a 6mm thick piece of plywood 32½” x 15½” painted a Terra Cotta colour. The centre section and other small areas had a thin Green foam sponge material stuck to the board to imitate grass areas but in the examples seen this has subsequently perished over the intervening years. A Grandstand and a Trackside Pit were included which were push-fitted over raised timber blocksfactory-built display layouts There were also various scenery items such as Fencing, Flags and Flag Poles and even some Figures which were included and glued into place. From a recently seen scanned photo it seems that one of these layouts was featured on Wrenn’s exhibition stand at a German Toy Fair.

There are three examples of this layout that have survived and subsequently been acquired as part of individual’s slot racing collections. It is likely that these were supplied as part of the dealer offer above since these versions included two special items not necessary when Wrenn originally took them to exhibitions. One was a specific custom piece of Barrier Fence with unique printing and the other was the inclusion of one of Wrenn’s cardboard advertising banners fitted onto two steel posts. The cardboard banners had been previously been used at exhibitions where a number of these were placed around the exhibition stand. The track itself included a Lap Counter and a Deflector Section and to promote the latter unique element a special short piece of Barrier Fence was produced. This was printed in Red with an angled arrow pointing to the Deflector operating button and with the words ‘OVERTAKING THREE CARS ON EACH LANE’. This Barrier Fence section also featured an angled end to emphasize the arrow. The special cardboard advertising banner was printed in three colours, a Turquoise background with Yellow & Red which was 18⅞” x 3½” overall and then folded horizontally. It featured the standard Cooper illustration to the left, ‘WRENN formula 152’ in Yellow & White and ‘FOR REALISTIC MODEL MOTOR RACING’ in Red to the right hand side. This was stapled together so that it could be fitted onto two polished stainless steel rods which were fitted vertically to the base via holes in flat timber blocks. The examples seen of this version of layout have included Trackside Pits with Maserati and Vanwall pit boards. Two layouts have been seen with E1 Controllers secured to the corners at opposite ends of the base with their separate rails and the other two have Mk II Controllers, so these layouts could well have been produced latterly since the layout that I own does not have any previously drilled fixing holes for the Controller rails. Finally Wrenn included one of their cars on the layout which didn’t have any internal components and the empty shell was just screwed to the baseboard. The examples seen of these layouts are all slightly different from each other, from the building positions, type of car included and positions of the figures which all differ.

There were three medium-sized layouts built, some with and some without the Wrenn railway track. The larger of these layouts seen is more interesting being the one featured in the 4th version of the A10 – ‘152’ Instruction Manual with a photograph and accompanying layout plan therefore dating its probable production during 1962. This is one which was subsequently acquired over twenty five years later in a very sorry state. The layout was fitted onto a baseboard with a substantial timber frame having a plywood top and being 4’-6” x 2’-6’ overall. This was painted, similarly to the other display layout baseboards, with a Terra Cotta coloured paint. Since the layout was basically on two levels the Track was supported on timber blocks as well as items from the Grey polystyrene T30 – Bridge Support Set. A paper-backed Green Landscape Sheet was used to imitate grass and to cover the landscaped areas. This layout included a Deflector Section, two Trackside Pits, with Cooper and Ferrari pit boards, as well as various items of Fencing, Flags and Figures. The landscaping of the layout was improved with model trees, a small river section, a supporting ‘brick’ wall and even included some of Wrenn’s Model Railway items such as track, points, buffer stop, etc. These elements were used on other subsequent factory-built layouts to enhance the overall appearance. The other medium-sized layouts had photos taken and these appeared in the Wrenn 152 Catalogues, Wrenn’s UK trade adverts and one of them even in a book, ‘The Complete Book of Model Raceways and Roadways’ by Louis Hertz.

The final, and largest, figure-of-eight layout appeared in the last Catalogue as well as in the current trade advert. This layout was actually used as the feature element in Wrenn’s exhibition stand at the Olympia Toy Fair in August 1961, where a competition was held over the week-end for the Olympia Sprint Championship. This was held in two categories for Juniors (9-12 years) & Seniors (13-16 years) but unfortunately with nothing for the ‘older’ racers.

There was another extremely large display layout built with Wrenn components. This was only featured in Wentzels current catalogue (see relevant International Market section) and was over 13′ in length. It is therefore assumed that it would probably have been built in Sweden specifically for Wentzels since the logistics to take a layout of this size abroad would have been far too limiting cost-wise for their limited market.
