This is possibly a question a Polish member with a better understanding of the language than I can answer; perhaps Michal S if you're still active on this forum?

Does anybody know what the KI of KI 170 stands for? I know the Wz. of WZ. 1970 stands for Wzor, which loosely translates to Model but am baffled by the KI initials.

I'm also intrigued by what KT-23 or KT-130 means on the supplied test card that came with these pistols. Does anyone know?
