Perhaps the correct "early" foresight protector is the waist-ed style, with LB and C broad arrow?
The LB stamped front sight showing inch measurement, a CCM nose cap under a LB marked and acceptance stamped hinged band. All this and many more "correct" defining characteristics on an unissued, pristine 1941 rifle. It does not get too much better, IMHO. Perhaps an EX in the white?
