What I find interesting is the USA, thanks to our millions of civilian shooters and long tradition of buying all of the other guy's surplus stuff, have (rightfully) earned the place as the world's premier dumping ground for old surplus gear.
Also, because of the ravenous demand we have as a collective, there's always a solid financial incentive for importers to always find new and innovative ways to make good things land in our cabinets.
In no small way, I wish I'd been around when Mausers were cheap. I've heard old timers (no offense) talking about walking in to gun shops when there were barrels full of the things. Now I can't find a good quality one that costs less than a modern premium rifle. SKS's went up in value (substantially) when no one thought they would... Enfields, same thing.. Swiss rifles, same thing...
I imagine the Mosin Nagants, someday, will also substantially appreciate in value once supplies finally dry up.
Which brings me to a point - those guns are becoming more and more iconic of
generations, than anything. The 1933 7mm Spanish Mauser I have is one example - my uncle Joe bought it when the things were cheap, took good care of it, and now it's become a family heirloom with no small story behind it.
So, make fun of the Mosin Nagants, or the Mausers, or the Enfields, or the SKS's...
Remember, someday those will be a valued sentimental piece that some youngster-not-yet-born inherits when he comes of age, and it will be appreciated - and used.
