You claim to be the only manufacturer of vz. 58 rifles and vz. 61 Pistols in the world, but I see many other dealer selling various non-CSA vz. 58s and vz. 61s in many different countries.

Yes, that is true. Czech Small Arms is the only manufacturer that makes both vz. 58 rifles and vz. 61 pistols completely new. All the other vz. 58 and vz.61 models from all the other „manufacturers" are either surplus, original full-auto firearms only converted into semi-auto firing guns or built from the „parts kits" using just few new main components, like barrel or receiver or stock parts.
