This is interesting, the markings look like savage but I'm not seeing a US property stamp on the top of the receiver. It looks like it might have been refinished at one point because the 1942 date has been scrubbed out a little bit. I was looking at long branch proof marks and none of the proof marks on your guns barrel fit. Also the English proof marks are very noticeable and your gun does not have them. If I had to guess it may be a very early savage made lend lease gun.
