I was a bit torn between a pre-production model shop job and a very late-war gun made in a hurry. I finally concluded it was the latter, based in part on the magazine catch. The 38H is a bit odd in that the gun originally had no slide safety, most of the production had it, then it was taken back out again in the very late guns to save time and production steps.
So a gun with no safety could be either early or late; I opted for late, but if anyone has other ideas, I would appreciate hearing them.
