Hello My Fellow Nuts,
I will step in the hot water one more time. I want you to keep in mind I only have one eye. So taking that into account I have also posted an image of what I see and what I have seen on the "Z" suffix block of 1937-S/42 pistols. It is a difficult suffix to figure out. I once had a luger enthusiast stand at my table at a gun show and examine a 1937-S/42 pistol in the "Z" suffix. After about an hour he still could not tell what he was looking at. Maybe I don't know what in the hell I'm looking at either. But here is what I see.
ZZZZZZZZClick on the Z's.
Regards,
