I traded for this old Win 62A some years back, and noticed it had what appears to be British proof marks and roll stampings. It's a bad picture, but it has rolled stamped right above Winchester ' 22LR .610" 8 TONS PER Square '
It also has M 192 crudely stamped on the barrel over 194 (?) mark.
Has a really nice Parker Hale AgA tang sight installed.
Serial Number is 14000X. Are these markings normal or was this some sort of lend-lease gun?
