This remnant trigger guard was once part of a Kentucky Rifle owned and used by James Butler Bonham (1807-1836) at the siege of the Alamo in which he lost his life along with 189 other defenders on March 6, 1836. Bonham met his death defending the east wall of the old mission. He was 29 years old. The original rifle was a 36 caliber model built in the late 1820's.
