So what have you bought the Scorpion pistol

or the Scorpion rifle? I ask because you use both pistol and rifle in your post. I had the Scorpion rifle in .177 flavour and it was superb. I sold mine about 18 months ago in favour of the BSA R10, again in .177. If it's the pistol in mint condition it could be worth a little more than your asking price, they're very collectable, particularly as they were one of the few pistols made that were able to achieve the full UK power limit of 6ft/lb.
