This triggerguard is an early design, used by the Rupp family and other gunmakers of the Allentown-Bethlehem, and Lehigh Valley. The sculptured, curved shape of this guard is apparently derived from earlier Germanic Jaeger hunting rifle triggerguard styles. Notice the thickened lug at the front of the bow to permit mounting a sling swivel, if desired. This feature was found on European hunting rifles and military arms. Early American triggerguards often retained the lug but omitted the swivel. Gradually this feature disappeared from American longrifles.
Overall length is 7-3/4", inside trigger bow is 1-13/16" long, and 3/4" deep.
