Hmmm, just looked more carefully at the serial number picture, you can clearly see machining marks below the serial number, that indicates a
Lithgow to me, Enfield and BSA made rifles are better finished cosmetically, with these markings smoothed off (not starting a Antipodean quality argument here guys), its just these markings are always evident on Lithgows I have seen and they are not typically present on
UK manufacture rifles.
The mystery deepens, don't know what it is about that rifle, but it just doesn't look quite right to me, just cant put my finger on it.
I wonder if its a civilian US made 922r compliant receiver, (minus Auto sear) L1A1, that somehow arrived over here and was deactivated, these have faux UK military type serials applied sometimes ??
Got me stumped.
