Regarding 3/70:
Per the above-linked navweaps figure, the turret should be 151.38" high from deck to top of sighting bubble, or 25.2px. My version is 26px high; heuhen's adjusted version is 22px. The overall length of the gunhouse should be 200" or 33.3px. My version is 35px; heuhen's is 30px. Overall length (muzzle to back of gunhouse) should be about 313" or 52px. My version is 54px; heuhen's is 46px. Clearance circle should be 248" or 41.3px; my version is 41px; heuhen's is 38px.
In every case, my version is as accurate or more accurate than the revised version. While mine could use some fine-tuning in size, everyone please make sure that any new version is more accurate than the old one. Less accurate does nobody any good.
We have the Scandinavian inches, we have the U.S., and we have the international. Guess what I used. It's also why my was completely wrong ...
