Factory, ownership, inspector. The "C Broad Arrow" is a gov't ownership mark and not a factory "Canadianicon Arsenals Ltd" mark. That buttstock was produced prior to the CAL changeover. Late production CAL butts have a tiny "A inside a C" stamped on as the factory mark instead of the "B inside an L". They're hard to find too. Anybody got spares? The spare wartime LB butts are common.
