The Czech Mausers were mechanically the same as the much-more-famous German Mausers and they were built largely on machine tools taken from the big German factories after the end of World War One. Machine-tools, if properly looked after, don't wear out all that fast (if ever). Czechoslovakia took over a big chunk of the international arms trade between the World Wars.
When the Nasties walk in in 1938, it was little trouble at all just to keep the factories cranked up, making rifles for the Germans. The original Czech VZ-24 had a front handguard and a barrel-band different from the German Kar98k model (which came out in 1935) but it was not a big job at all to change that over while production kept on full blast, just using up the parts on hand. After that, the only way you could tell a Czech Mauser from a German one was by the factory codes stamped on them.... if you had a code book.
There were quite a number of Czech rifles built as scoped snipers in the 1930s, including a big batch for the Romanian Army. A lot of the German top shots seemed to feel that the Czech rifles were built better than their own, although it is pretty hard to see just how.
They were good, really good.
The biggest drawback is what has been pointed out above: modern ammo is just loaded too light. You can really zip it up by loading your own. Get 3 or 4 boxes of factory stuff and bang it off at cans and seals and stuff like that, then sit down and reload it. Same power as a .30-'06 is completely safe in a Czech Mauser. And it WILL flatten your Moose, even those big ugly ones that stand in the middle of the Road to the Isles all darned night, up by Notre Dame Junction!
Good luck, friend!
Nice toy!
