Good to see someone up for a new parts sheet, but expect a lot of nitpicking!
Re. the template, are you sure about the style of that flag? Looks way too photographic to me.
Scale is 2px = 1ft, i.e. 1px = 0.1524m, i.e. 1m = 6,5617 px
Doesn't change that much from your estimate though.
Side note: Are you interested by the turrets and mounts I made for the WW2 river gunboats
a while ago?
