The 99 is a killer deal. Most of the one’s I see are beat or later models with that awful pressed checkering. I’d wager that one is 1940-1950’s vintage. I have a 1938 takedown model in the safe that is very low mileage (the case colors on the lever are very bright), in 300 Savage.
Nagants I don’t mess with, a personal rule not to buy commie guns. That way you don’t have to check the muzzle for the neck hairs of some zek.
Looks like a genuine Krag that was sporterized, and not one of the Benecia Arsenal carbine conversions done in the 20’s. The integral front sight is the tip off, the Benecia ones used a 1903 Springfield band sight.
The Colt 1903 and 1908 are great guns (Bronwing design, how can we expect less). My 1908 is the least ammo sensitive .380 I’ve ever seen.
Based on the bluing and wood finish color the A5 is a 1950’s gun (the sweet spot for Belgian A5’s). Shame about the Cutts, they pattern well, but are loud. Tubes are still available from Midway I believe, or small dealers like Don Corson of Corson’s Barrels (I got a .410 Cutts tube from his for a Winchester Model 42). A possibly “folk legend” story was that in the 50’s a Soviet shooting coach bought up a Cutts equipped gun at an international meet and cut off the barrel to take it back for study. That led to the “Tula” Choke that was popular for a while.
PS: Shouldn’t gas have been 3.10 in Yuma?
