The internal extractor was used up until 1962 and really was not in full production until IIRC. So this gun cannot be any older than 1962 but the serial number is too low. Looking at the serial number on the gun it should be a Pre War Hi Power but it does not have the internal extractor or the older style slide with the thumb cut.
It also shows the Browning Arms Company Rollmark Utah & Montreal which did not exists when a gun serial numbered 10014 would have been produced. Prior to the Utah Rollmark Browning marked guns had St Louis Rollmark.
Strange....
