This is a magnificent model and was at one time operable and able to submerge and surface on command. Modeled after an American WWI era ship, the "237" on the conning tower could be a reference to the SS 237, the Trigger, an active submarine in the Asian theatre during the war. This model still has most of is electronics intact but needs a complete reconditioning before being put back in service. It features a detailed tower with rigging and its size is impressive. 50" L x 5" W x 11" H. LOCAL PICKUP ONLY!
