bluebayou: Being the moderator on this site doesn't mean that I know all to end all and you may be perfectly correct. My thought is that if it's a VZ-24, or started life as a VZ-24 but then was factory re-worked at Preduze 44) then its a VZ-24 action with a newer barrel. I have a VZ/CZ 24-52. When I purchased the rifle I was told it was a VZ-24 that had been factory reworked at the Preduze 44 (factory) in 1952 and had been rebarrelled, but it was still a VZ-24 action.
I also have a VZ-24 WWII bring-back that has the same size action and barrel length as the 24/52.
I also have a M48A, which is a different critter. The bolt from the 48A is shorter than the VZ bolt and is not interchangable and vice-versa.
I'm thinking (hard enough to go for a 2nd cup of coffee) that possibly the Preduze kept the modle 24 moniker but I don't think they are the same action.
As for a 2nd opinion - I think I'm handsome...................Mikey.
