I inherited this gun and kept it around for quite a while now even though it was missing a part. I just liked the look and age of it. It has a short octagon barrel on it, so wasn't sure if it may have been cut down at some point in time or if they possibly made short barrels (24 inches.) I have researched some on the lock maker G. Goulcher placing that from somewhere 1840 to 1860. Any information and approx. value would be appreciated.
