Thank you for the explanation!

I cannot remember to have seen this earlier, but at that time, I had not built any submarines.

I have only 1/700 waterline models of submarines and some post-war USN submarines are still missing. Bill's Bits n Pieces provided some of the missing, especially the Virginia class. I think also that his Trasher and Sturgeon look much better than the earlier JAG kits.

My other USN submarines are built using Hobby Boss, WSW, and OKB Grigorov kits.
