I didn’t know the Czechs made Makarovs (or the Rumanians either).
I know the Poles, Russians, Bulgarians and E. Germans make or made them. Mine is E. German, from the Ernst Thalmann Werke, named for a Red thug killed in street fighting with the Nazis I believe.
Mine is Bulgarian, imported through Virginia Beach.
The Hungarians made or make them , too. It was a Russian franchise.
