Hello.

I have a HW45 .22, I have not used it for ages. I got it out and fired a hand full of pellets the other day, it is still shooting nice tight groupings. So the gun is perfectly servicable.
However I dont think I'm going to get any further use out of it and have decided I want to sell it. I cannot find anywhere to sell it though and I have no idea what its worth.
Can anyone advise me A. how much its worth, and B. where I can legally sell it please?

Many thanks in advance
