above : WDAD U Class submarine
below : SH5 U Class submarine
why ? because there were two types !

The first three boats, HMS Undine, HMS Unity, and HMS Ursula were ordered in 1936, and during construction were modified to accommodate four internal and two external bow torpedo tubes.
They proved to be useful warships in the confined waters of the North Sea and particularly in the Mediterranean. A further 34 vessels, forming the third group, were ordered in 1940 and 1941. They were similar to the second group, but were lengthened by 5 feet to provide a more streamlined shape. All but two of the 49 boats built were constructed by Vickers-Armstrong; the exceptions were HMS Umpire and HMS Una, both built at Chatham Dockyard. The submarines were powered by Paxman diesels generating 615 bhp (460 kW) and electric motors that could put out 825 shp (615 kW) giving a surface speed of 11.25 knots (21 km/h) and a submerged speed of 10 knots (19 km/h) .

One of the most famous U-class submarines was HMS Upholder, commanded for its entire career by Lieutenant-Commander Malcolm Wanklyn. Wanklyn received a Victoria Cross for attacking a well-defended convoy on 25 May 1941 and sinking an Italian liner, Conte Rosso. In her 16 month operational career in the Mediterranean, before she was sunk in April 1942, Upholder carried out 24 patrols and sank around 119,000 tons of Axis ships – 3 U-boats, one destroyer, 15 transport ships and possibly a cruiser and a destroyer. Losses in this group were high, however. Only three out of the twelve survived the war.

so should we make two types in WDAD ?
the model from SH5 is the first type with 6 bow tubes including 2 external
the model from WDAD is the later type with 4 bow tubes.
