OK Team, Ive managed to find out on the Web these are Ferlach proof marks, and Austrian Maker but actually proofed in Prague Czechoslovakia. The marks on the net say handgun but this is a rifle and they are the correct marks.
I think that code tells me the year of manufacture....does anyone know??
Cheers and thanks in advance:):):)
