Soviet S-13 Stalinets Submarine

Read about S-56 in Vladivistok, stumbled onto the production value of this class of sub, also did some reading about the sinking of Wilhelm Gustloff by S-13 and low and behold, the only S-class kit I can find is a ship I want to build and the scale I like to do subs in. The hull is green because according to my research, that is most likely for S-13 due to the fleet in which it served, the Baltic Fleet.
