The Swiss CZ is the real deal. It has the CZ factory papers etc. CZ-USA is wrong on this one. CZ-USA did not exist at the time. CZ-UB did not even exist at the time as a name, all production was by AGROZET National Enterprise at Uhersky Brod (Agrozet was the government enterprise that produced the CZ-75, among many, many, other things, when the state-owned Precision Machine-Tooling Co., Uherský Brod was merged with it in 1983. The arms production became CZ-UB upon privatization). The CZ logo was retained and used for small arms.
The numbered paperwork, including the target, are labled "Producer: Presne Strojirenstvi Uhersky Brod" I have everything, including the labeled Engineering Inspection sheet and the test target is the real target that was shot, not a printout. The pistol is fully proofed and dated.
Remember, CZ-USA also did not exist nor were they part of the communist business arrangements made at the time.
The book "The CZ-75 Family" by J. M. Ramos was published in 1990, several years before CZ-USA was established, used as its source Action Arms, the CZ importer in 1990, as well as Agrozet itself , which was CZ-UB as it was known at the time. Also sourced was ITM as well as Tanfoglio (and FIE and Excam, both of which were still in existence). Basauka was the importer at the time, and they legitimately imported CZ-75 pistols. Merkuria was the export arm of Agrozet during communist days. The book was published just as the 75b was being developed, initially as the CZ-90. The final designation, capitalizing on the 75 pedigree, was to be CZ75b.
According to Agrozet and ITM, (remember, this is CZ-UB under communist direction), "The development of the AT-84 pistols series was undertaken by ITM in Solothurn, Switzerland. Through a joint venture with the Czech weapons factory and its export company, Merkuria, ITM was to produce the CZ-75 in its original configuration. For a short while the venture seemed to work well, but eventually the relationship deteriorated and ITM decided to break the partnership." (Ramos, JM,
The CZ-75 Family: the ultimate combat handgun, 1990, Paladin Press, 62-64)
A small number of CZ-75's were made in Switzerland, proofed by CZ-UB, which was known by Agrozet, exported by Merkuria to the US, imported by Basauka.

I sure don't intend to trash CZ-USA, but that entity is an import company tied to CZ-UB currently. Nobody at CZ-USA was part of the arrangements made in the early 1980's by Communist Czechoslovakia, ITM, and Basauka in the US. All of this happened a decade before CZ-USA was organized. CZ went through two other importers after this arrangement and before setting up CZ-USA. Both Action Arms and Magnum Research were CZ importers after Basauka and before CZ-USA.
Remember, CZ-USA was never involved with the importation of the original CZ75. (The current 75b was originally called CZ-90 during the prototype stage incidentally). CZ-USA does not nor did they ever warrant the original 75. Indeed, CZ-USA does not have any official or legal responsibility to the CZ75 pistol.
