I recently spotted a French MAS 1936 at a pawn shop. The stock, although in good shape, looks like it has been replaced or modified because the parts don't exactly match up well. Or maybe this is normal for some MAS rifles? Bore looks good (7.5) and has bayonet. They are asking $150? What else should I be looking for besides the obvious when purchasing this gun? Besides the obvious serial number engraved in the metal where are the other serial numbers? Should there be one on the stock anywhere? I noticed after looking at many pictures online that some guns had serial numbers on the stock and some don't. Any suggestions, tips, advice would be much appreciated. Thank you.
