My Dad had both an Enfield No.2 .38 revolver and a Beretta M1934 squirreled away in the garden shed post WW2 RAF service. After he died in the late 80's my Mum told me about them, and decided I should have a look for them.
I found the revolver fairly quickly - a hefty piece of kit. It was loaded with 4 rounds, but that was all the ammunition I could find. It seemed to be in decent nick. The Beretta was in an old hairdryer box, with a full magazine and one round chambered. Again, in good nick, and I had no problems with the moving parts and unloading it.
Mum then suggested I take them to the local police station to hand them in. I smiled sweetly, and told her I would drive her to the station and she could hand them in - there would likely be far less questions. She was in & out in less than 5 minutes ....
