Very similar to #TG-SPW-A-B, but without the thickened boss at the front of the bow, this is commonly called an early Lancaster County triggerguard. This style was sometimes used by Jacob Dickert, Peter Gonter, Abraham Schweitzer, and others shown in Thoughts on the Kentucky Rifle in its Golden Age by Joe Kindig. Sand cast, soft malleable brass.
Overall length is 9-3/16", inside trigger bow is 2-1/4" long, and 7/8" deep.
