I’m betting there are some old 30-40 Krags laying around those mountains too....
Been a while since I've seen one. M1 will have to do.
Not too long after the Cuban Revolution of 1959, I had a nice little sideline rebuilding Krag barreled receivers, which I was getting for $1.50 each, into sporter rifles. Ammo was provided after I swapped a couple of cases of .30-40 blanks from the local American Legion, which used '03 Springfields as salute rifles and had received .30-40 blanks by mistake, with M1909 blanks for the Springfield, on a one-for-one direct exchange basis. The guys were even nice enough to let me have their once-fired brass, .30 and .30-40 both.
About 1964-'65 I got some very polite queries from some folks with Miami connections making me a pretty good deal on Krag bolts and trigger guards, they being about the only things getting a little hard to find from the DCM or on the surplus market by then. I jumped at it and had enough components to finish up a couple of thousand more rifles. And it was very casually asked if I thought the Krag action and bolt could be reworked to handle the 7.62 NATO/.308 Winchester action. There's only one locking lug on a Krag bolt, and I thought it wasn't a real good idea. But there's only a single locking lug on the old small ring M93 7mmx57 Mauser carbine, and the Spanish did indeed rework some M93 and M95 carbines as police and reserve rifles when they were just starting to manufacture and issue the CETME autoloading rifle in 7,62 NATO that became the German H&K G3 and HK91.
And yeah, there are indeed old Krags and Spanish Mausers scattered here and there all over the world. But they're better used as what they were and what they are, rather than try to make a silk purse out of a sows ear. It's almost always more work than it's worth.
