This an ORIGINAL 30-B rear site for Winchester 1906 (and also used on the later production 1890 model pump .22 rifles). This is a COMPLETE 30B sight, with a shorter length than the earlier version and with a longer base, that includes the attachment screw, with the elevator screw (that is our replacement part No. WP45P.) just behind the V-notch on the sight. A Winchester Patent date of 1901 is stamped on the arm of this sight.
