George, I am under the impression that VOPO's were simply what they had left over. i.e. if they had guns in stock/storage/given back to the East Germans, they took them and used them?
I am pretty sure that I have seen
either a VOPO or more likely a Russian capture sear safety. But that does make for an interesting thought.
BTW, here is the original thread that I split;
