Re: does somebody recognize this weapon?? or give some info?
It is a box lock, probably pre Civil War, don't shoot it. I've seen two antique brass-barreled pistols with the sides of the barrels ruptured. One had the left side of the barrel blown out, hope the shooter was left handed, but since that gun was part of a country doctor's estate, I suspect somebody at least got a load of gas in the face, if not schrapnel.
The other was on display at Mt. Vernon--a matched pair of flintlocks that belonged to GW. One barrel was blown out, no explanation given although both were prominently displayed.
