So, I believe, as I said, that he built this thing out of pride, because the effort made to build it would have been enormous.
In the late '50s when I was an apprentice, in Hungary,we had lots of precision german machines.We made some real jewels just for fun,in our lunch/spare time....
So, here's my question: If a very skilled individual spent a lot of time and effort making this pistol, wouldn't he put his name, initials, crest or some other identifying mark somewhere on the pistol, other than "1944"? Even if I were the humble type, I would stamp or engrave my name or at least initials on the inside of the grip.
