Marc,
I think the stamps you noted on the frame and receiver are British proof marks. I agree that the stamp on the rear toggle link looks like an Erfurt proof and this gun certainly is a mix of parts with an interesting history - not sure it's a VOPO, might also be a Russian capture, or who knows what.
Peter, I am interested in the deactivation. I can see a big hole in the bottom of the receiver/barrel and undoubtedly the firing pin is ground off. What else was done that is not visible in photos? The frame looks intact and in the US the frame is the part that is subject to regulation. It appears from your photos that if you replaced the barrel and firing pin the gun would be "good to go."
