I am about to clean a pistol for a customer, a 29M, slide marked "FEGYVERGYAR-BUDAPEST 29M", serial number under 12000. It is not marked FEMARU. Hungarian crest on the LH trigger guard.
The bigger question regards some hand stamped markings on the LH arch above the grip safety.
"6.KP.200." Are these specific to a unit, police group or other identifiable entity?
I can post pics if necessary.
