Hello mud, sorry but I just saw this post. A picture would be nice but I am 99.9 percent sure of what you have. Is it very short with a rear peep sight, front sling swivel, rear sling attatches on the side of the butstock (vs the bottom ) and probably no safety unless you have one that has a simple push pull (basically a piece of flat stock metal ) safdty that blocks the trigger.It is a sporterized version of the last bolt action rifle adopted by a major army. The French MAS model 36 in 7.5 x.54 . I have one and the caliber is not marked on the barrel. I would think that if it had been rechambered that the new chambering would have been marked on the barrel. It is a handy little rifle. 7.5 x.54 MAS cartidge falls between a 3006 and 308, uses a 30 cal bullet. The down side is that it is French ! Because it is an odd ball catridge nobody wants it ( cant get it at WM or LGS) and they are not worth much if anything. I love mine as I have hunted with it for decades, its light, small and we have some history together.
