Hello Everybody and Merry Christmas. Can you give me some advice please on the BSA Scorpion pistol, my local airgun shop has one that seems to be in very good condition, the asking price is £150, is this price ok or too high. I understand that he being a dealer needs to put a bit of a mark up. If the price is right what do I need to look for in the pistol (seals, rust etc.). Thanks for your help Lucio
