***I remember an old lady bringing in her late husbands single shot rifle that hadnt ben used in some years.***
I remember reading of an elderly woman bringing her late husband's guns to a buy back. The firearms were an almost new Colt 1911 and an almost new Springfield 1903 rifle he had purchased just after the first world war in 1918.
The cop on duty suggested she take to them to a gun dealer for a quote on them as they were true collectors firearms.
The cop was later repremanded by his superiors for this action.
Of course he was, you can't get them "off the street" if they are taken to a dealer.
