25/05/2023. U65. 14". 410g. Tinplate Clockwork Diving Submarine.
U65 has a two plate 0.2mm steel hull with a 40ml ballast tank in her nose, the vent is just aft of the screw cap winding port through the fin, she has a powerful 4 gear single spring motor driving an anticlockwise 3 blade prop (she also winds anticlockwise, a bit weird but that's just how I built the motor). This little beauty is a commission and the brief was a bit of a blend of U52 and the French J.E.P. Nautilus. I think I got it close, the commissioner is happy! Job done.
