Imperial War Museum Construction Sets

The Imperial War Museum (IWM) sold some metal construction sets under their own name. An interesting thing is that these sets combine both Meccano and Eitech compatable parts. i.e. Both Imperial and Metric parts. These construction sets can be classified as Polylong(1a) type sets.

From the style of the box and packaging, these are almost certainly made by the same Chinese company that makes the Haynes/Demand Media/Coach House sets. Interestingly the IWM model of a Hawker Hurricane, the Haynes model of a Spitfire and the AtoZ model of a Spitfire all appear to be the same model.

Imported from China by (Smart Fox) Koch Media, Reading, UK
