I picked up a box of WWII diving equipment yesterday and am coming up pretty short on info. Its called a Shallow Water diving kit, made by Thompson Engineering Company (TECO) from Grand Rapids, Michigan. The rubber mask is a designed from modifying a gas mask. There is a lead weight belt and the breathing appartatus. The original instruction manual is still with it, as well as all the fittings. The only thing missing appears to be some "brass slippers". and possibly a small tank. All is in very good shape and very cool. The vets obituary states he was a Machinist Mate 3rd Class in the US Navy. I picked up several of his uniforms and some of his equipment also. I didnt pay too much for it, but i guess it wasnt cheap either! Any info would be greatly appreciated!
