Only the left side of the receiver has been unwrapped so the dealer who imported it could get to the serial number. The rest of it is mummy wrapped just like it came from the arsenal. It's in 7.5x54. Serial is 43XX. Paper attached to it says Jan, 1976. I suppose that was when it was made or arsenal refinished? Or was that when it was wrapped up and put away, or was that when it was sold and exported? I don't know. I'll leave that to the experts on this rifle. Here's some pics of it. It doesn't get any newer or in more excellent condition than in the cosmoline mummy wrap. Came with an excellent condition sling (I think sling has never been used), and a manual too. I'd like to trade someone for a nice MAS 49/56, but only in the original 7.5x54 caliber, not those Century Arms (C.A.I.) .308 rechambered ones. But if no one has a MAS 49/56 they want to trade, I'll take $475.00 for it.
