I recently purchased a postwar Czech K98K, 8mm. It has a scrubbed BRNO marked receiver, four digit serial no. with capital K suffix, matching bolt body, unmarked safety, unmarked cocking piece, lion proofs on barrel and receiver, and the barrel is marked with a dot 11 shield, LF, and a stick eagle 83. The trigger guard and floor plate are machined, marked with matching four digit serial numbers and both stamped with stick eagle WaA83. Neither the front or rear sights are marked and there's no front sight hood. The walnut stock is not original, as it is an Israeli engraved 7.62. It has no markings on the butt cap or the bands. It has not been milled for a cleaning rod. It has the various markings as shown in the photos, the most interesting being what appears to be a six digit serial number in the barrel channel and the circle 5 and 7 marked on the recoil block. Can anyone help me with determining the origin of the stock? German? Belgian? Czech? Thanks
