An earlier, heavier triggerguard, found on early Allentown-Bethlehem and Lehigh Valley style longrifles, by the Rupp family and neighboring gun makers. The lug at the front of the bow permits mounting a sling swivel if desired. American longrifles used for volunteer militia duty may have been required to be fitted with sling swivels.

Overall length is 8-15/16", inside trigger bow is 2-3/16" long, and 1" deep.
