Mausers are large ring or small ring.
Except for Turks. Originally the Turkish army had small ring Mausers. When they adopted the 1898 Mauser (large ring) for thier own use, they modified the design in several ways to make it the Turkish 1938. One of the mods was, while it has the large ring outer dimensions, it has the barrel shank and threads of a small ring Mauser. That way, all the older barrels they had could still be used on the new recievers.
So......the Turk is kinda a bastard. Externally its big and heavy like a large ring, and fits stocks for large ring guns. But if you want to rebarrel it, you'll need a small ring barrel. Also, there is hesitation about building custom big bore sporters out of these because of the reduced barrel shank size. The workmanship on them doesn't compare to Czech Mausers either. The workmanship and small shank barrel are reasons the VZ24 and 22/98 are more highly desirable and cost more. You can usually find a good looking Turk for $100 at a gun show, while a Czech gun will be covered in cosmo and the finish worn off at that price.
