The difference between Gato & Balao class sub's was how thick the steel in the pressure hull was. Gato max. depth was 300 feet. Balao's went to 400 feet of depth with ease. USS Torsk, being a Tench had mechanical differences, but appeared similar externally. The 1943 Gato would stand in for a 1945 USS Torsk without much fuss.
The GUPPY 1B is kinda similar to a Fleet Schnorkel boat. Since people can easily refer to the actual USS Torsk for comparisons, slapping a sharkmouth on the GUPPY 1b might not fly. Notice the GUPPY 1b rounded bow and the old-school bow bullnose on USS Torsk.
