I will add that although some Turk Mausers are well maintained and in good shape, some are far, far from it. I've seen multiple Turk made 98's with the primary locking lugs worn so badly they had significant wear on the third safety lug! Many Turk made 98's don't even seem to be case hardened, which is probably why they wore so badly. Doesn't seem to be a strength issue, just a durability issue. As bearhunter mentioned they used all sorts of Mauser actions and many of them are top quality like the German 1903's but even those often have seen very heavy use. They shot the daylights out of some of them.
