i have 2 MP-34 kits. on the fire control selector one has "T" and "S" the other has "C" and "A" i looked at some internet language translators and came up empty. also one has a top cover with a safty notch, the Steyr logo and welded over markings. the other has a top cover with no safty at all and no markings at all. my question is what country used these?
