In the 60's and 70's the milsurp market was awash in South and Central American arms. 7mm mauser ammo sold for $5 per 100. There was a lot of Argentine 7.65mm around, as well as the guns. Prices ranged from $20-$30+. They were suddenly dumping their bolt actions for semi or select fire weapons. These were mostly Mausers, and the numbers were considerably fewer in total than the Mosins. Back then there were some Mosins coming out of Spain and Finland, and maybe even Korea, 91/30's for $15 and M38's for $20. I'm looking at a Sept. 1967 issue of SHOOTING TIMES that I found recently in a box. You could order stuff through the mail back when, with no paperwork. M1 Carbines ran $60. You have to figure that, given inflation, the prices on most, except for the Mosins, are roughly 10 times what they were running back 40 years ago.Oh, MNs may become a bit scarcer in years to come, at least the collectible ones. My dad says that back in the 70s the South American Mausers were so plentiful you could hardly give them away. They are available still but not as much as in the past. I'd say Mosins are far and away the cheapest milsurps on the market these days, and they may not be that way forever. Available, but in smaller quantities, and therefore, a bit pricier.
Somebody correct me if I'm wrong about the SoAm mausers.........
