I totally understand.
It's not like we know what real WW2 ships really looked like. We only see what's printed in books and posted on the website... And by no means should we be limited to that media. I'm sure plenty of WW2 ships were not photographed. Actually, I wouldn't be surprised... WW2 historical documentation is okay, but it is lacking...
I say make your boat look good... make it look like it could possibly be from WW2... and I'll be happy!
