This rifle was listed on Gunbroker in July 2013. The GB auction specified a Sept 43 barrel which would be correct for a "Z". I have my doubts about the stock. By the time the "Z" series rifles were assembled I think the soks would have bee sourced from Keystone. Also my notes fom last July indicate a full complement of inspection and accreptance stamps (RA, Ordnance Escutcheon, FJA) Its looks that only the FJA is present now. The rest of the details seem unchanged.
