09/08/2017. U37. 22" Tinplate Clockwork Submarine
U37 is based on the early German WW1 boats , its a dry hull with a single ballast tank in the bow. The brass deck gun is fully articulated and spring operated firing a 3mm projectile. This particular submarine is available in kit form , the kit contains the parts in the picture at the top right , which is exactly what I used to make the boat myself. (some assembly is required).
