The pictures are not much help. As Dwight stated, 1917 should be stamped on the left frame rail. Also the take down lever and the sideplate should be numbered in the commercial manner rather than military. As large as the pictures are of the C/M acceptance marks, they do not show any real detail. The C/Ms do not look "right", IMO, however, not certain that "distance" between the two is a valid criteria for criticism. Don't know what we have stamped on the underside of the barrel, can't really see it; Brit stuff? I would not buy it.
