The M-N's are very common, and in original configuration, very good condition, no scope, wood stock, are well under $100. Ammo is as common as dandruff. Especially CHEEP milsurp ammo.
The 8mm Lebel is somewhat uncommon, ammo is not an everyday thing.
If you would like a M-N, take a stroll over to auctionarms.com, or gunbroker.com, and scroll thru the auctions. You WILL need to add shipping costs, and paying a dealer at your end to receive it for you. Or spend the $30 for an 03 Collectors FFL, and order your own from Southern Ohio Gun- or any other wholesaler- and have it delivered to your door.
