Going to tag on here the build log of my Sheerline Trafalgar Class sub built in the guise of HMS Trenchant
this picture is the bits that came with the hull I dont think anything was missing because although the sub was made by mr Sheerline I aquired the kit from a mayhemer as a swap.
This picture is the two hull halves as you can see I reatached the nose on the bottom hull due to this being the first part of an S or Z cut which I didnt like and wouldn`t work with the catch system I wanted to use
Picture shows the flood/drain holes in the bottom hull along with parts of the rear dive planes
Picture shows the front dive plane front flood/drain holes and some mesh over the holes to stop anything getting taken in to the ballast tank that could cause problems
