A long deceased chum of mine, an old Warrant Officer in the RCAF for many years, did numerous one piece stock conversions of the Lee Enfield, doing about one a year.
Everything he did was totally reworked, re-blued and of unmatched quality. If this one shows signs of having been refinished it might be one if his.
Lines will be square, sharp and the polishing will be of superb quality.
We are going back about 40 years here............
