As best as I understand it the Czechs used the Turk contract to clear out all of the Gew98 clones. They took all of the Army inventory as well as new production long guns and shipped them out to Turkey. They then began production of short barreled VZ-24's for Army use. I have a long barreld Gew98 clone out of Turkey that is marked VZ-24. So I guess the marking VZ-24 initially did not refer to the short barreled rifle. The Czechs really took their time making these rifles and they are nice additions to any basic Mauser collection.
I note in the photos that the triggerguard pictured has a German WWI stamp on it. Very common, as the the Czechs had piles of German parts as WWI war reparations.
