One of mine, currently this Dart brand full stock .45 caliber percussion gun hangs above the fireplace in our living room, along with a powder horn. (EMPTY horn and unloaded gun). We only use the fireplace on special occasions and I take the gun down when it's in use.
It is a very good shooting gun. I've been told that Dart was the importer probably in the 1970s.
The barrel is marked Dart .45 CAL.
