Well after I started this I was given better reference. So I'll be starting over from scratch on this one, but it's not forgotten. I'm sure I'll get to it later this year.
Turns out what I built didn't have the correct profile, especially that area around the belly dimple, but now that I have accurate cross sections to that it'll be a cinch to get right next time. I also wasn't quite sure which hull plates were raised and which were painted/scribed etc, (now I do), so I went into it kind of blind.
Anyway thanks for the interest, I'll get to it pretty soon.
