If anybody has watched any of the CZ “factory tour “ videos, you’ll see how the frames are cast, using what is basically the “lost wax method “ which has been around for literally 1000’s of years..Point is, CZ can whip up another batch of these anytime they want, as it costs very little to make the wax molds for the frames. Knowing that, I would have very little faith in any “limited production “ anything CZ makes, because it’s only limited until they decide to run another batch off, and that could be next week, next month, next year.. Best advice I could offer, is to buy them, enjoy them for what they are, but don’t fool yourself into thinking that there’s only a few out there, that could change anytime..
