Thanks for the tips, I’ll check out the sites. It’s an Air Arms S200 pump up type with nice Simmons scope, had it from new about 15 years ago I think. Trouble is I went to use it the other day after not for ages and it seems to not hold pressure now when you pump it up (maybe a seal gone?), makes a little phut and I now suspect there is a pellet stuck in the barrel. The gun shop quoted some ridiculous figure to fix it so this, and because I generally can’t be bothered, means I was just going to flog it needing to be looked at and repaired. I will ask the gun shop to buy/value it but I suspect they’ll make some daft offer saying it’s old, busted and not worth anything – I would rather test the market elsewhere too, to see if I can get a tad more for it. I know it’s probably like old used bikes you are attached to, you probably think they are worth more than they really are…
