Build your own real working model!
Age 8+ model kit.
It was developed during the Second World War. The idea for the M12 was first proposed in 1941 and the pilot - T6 GMC - built and tested in early 1942. The Ground Forces initially rejected the design as unnecessary, but after the Artillery Board supported the Ordnance Department, 100 were authorised and built, which were at first used for training.
bought this and a few others as Bordem killers and to teach my children how to follow plan a quick introduction too model building. As they only snap together they maybe to easy but the results are all the same.
