Your rifle is still not difficult to correct, barrels, sights, op rod and SA GAW stocks are still around.
My friend (who travels around doing estate sales) found this 2.7 with SA 4-44 barrel in a remote area of Wisconsin back in the 90's. He called me and said there wasn't interest as the condition was not that good, I told him to buy it for me. It was a veterans estate and the only rifle, rest were 22 rim fires and shotguns. Every part is original from April 1944 and has a nice bore too. I even test fired it at 100 yards using different lots of M2 ball and some AP, everything worksAttachment 110146Attachment 110147Attachment 110148Attachment 110149
