Ok guys, I appreciate all the comments and suggestions that you have offered. I have gone over the gun with a 10x glass and can find no trace of an importers mark or indication of a brass plate or solder remanents. It is obvious that the gun has been refinished at some time in its history, but apparently long ago, as the fine pitting is in the present finish. It does have a 1925 date stamp on top of the bbl.
I also discovered this Vickers proof that was under the safety lever in my previous photo.
