Rich, this is absolutely STUNNING work!! I've been studying your pictures here to see the fine Sherman details.
I have a LOT of books on the Sherman and I've been wearing them out researching what goes exactly where. BUT I CAN NOT find any CLOSE UP pics of the turret gunners' periscope (the one right in front of the commanders' hatch. Even on the web, all the pics are at a distance and hard to make out. This Sherman book I purchased a few months ago is outstanding in detail pics but not that much for the periscopes.
Where can I get pics of the gunners' turret periscope for an early M4A3 (75) small hatch Sherman?
