School: Rowan (North Carolina/NC)
There were three Henry Bruners- Henry Bruner Sr. (1719-1769), Henry Bruner Jr. (died 1803) and Henry Bruner III (1789-1819). The Bruner’s favored the patchbox release button in the toe plate and not in the upper sideplate of the patchbox as found in most Rowan School rifles.
