My late buddy Brad, had this one, in 1/2 stock - with engraved action. Calibre was 9.5x47R (9 1/2 x 47). The action appeared to be of less quality than my M71/76 Mauser Carbine, and was also slightly smaller or reduced in size. There were no identification marks anywhwere on the rifle's barrel nor action. A chamber cast showed us the ctg., which was easily made up with rudimentary tools and other dies.
