After about 1840, factory produced locks became widely available. Sometimes marked with the maker’s name, often marked “warranted” to assure confidence, these slim percussion locks became popular on Ohio rifles and Plains rifles.
This Ohio Rifle style Warranted cap lock is fitted with a fly detent for use with set triggers, and a swivel link with integral pins for simplicity and speed. This cap lock is pre-cut for a 1/2” drum.
This lock is shown at exact-full-size, in Track's new catalog for gunmakers and gunsmiths.
