Thanks.
The proof mark on top of the front sight base means tha the front sight has been replaced, most likely at the same time the hold open was added. There are no ser# on the barrel and the alignment mark at the front sight is missing which tells us that the barrel is likely a reaplacement.
On couple of those pics it looks like there is a faint proof mark on the right sight of the chamber which is correct.
Also it is possible this pistol has an early reblue as the pin for the hold open should be in white, not blue. That could also explain the faint proof marks.
Please correct me if I�´m wrong.
