In the mid 1980's , I was visiting the 1860's Harper's Ferry military Arsenal , W.Va.. . After that , the girls went antiquing with us guys yawning in drag. Just as I reached the totally bored level , in a corner of a shop is a box labeled , "old gun barrels". The box contained about 8 breached original smooth bore pistol barrels for $35. I whined and so on to the clerk and the price was adjusted down another $5. Took the box home and dumped it on the workbench. Each barrel seemed to be a cut off smooth bore musket barrel. Contacted Kit Ravenshear and he said each would make a classic 18th century "Horse Pistol". Each barrel had the breach plug tang broken off in an attempt to demilitarize them. Kit had a welder and put the proper tangs back on the barrels. Each barrel had it's original musket Proof marks and a couple had 1800 era date of manufacture. The bores , .69 through .78 were rusty w/o too much pitting and very serviceable. The hardware store had a 3/8" steel rod to cut off and slit the end to accommodate strips of emory cloth , a little oil ,electric drill motor , and I was in business polishing the bores. I still have one left and might make a rattle snake blaster to put in the UTV on trips into the back country. A load of bird shot , w/hornet nest wadding , safely dispatches those critters . ..........oldwood
