Hi There, My father died a couple of years back, and left a Colt navy six shooter black powder.My brother purchased this new for him when he lived in the states in the early eighties. The store he bought it from"de activated" it for him by putting a lump of lead in the barrel, it has never been shot. So my question is, can I just sell it on , or do I have to hand it in to the police given there is no fac.It seems a shame as its brand new.
