Hello Ed,
Your doing a graeat job on this S-100 boot, looking at your pictures I have to make one remark.
It is very visiable on your pictures you for got to use putty on the filling plates  of page 1 of the italery manual.
I mean part numbers 5e, 6e, 7e 33d and so on, these plates are not on the original vessel and are just for the model to fix thehull parts and after that the deck.
My compliments on your torpedo's they are looking very natural to me  .
Just one advise when you finaly place them on the boot besure that the fins are
horizontal and vertical they work just like the fins of a airplane vertical for the direction and the horizontal for the deepth in the water.
Keep showing us your pictures !!!
