I have a like new .22 BSA Scorpion pistol that I am considering selling,but I am not sure of the value of this gun.It includes the original box,cocking tool,oiler,pellets,and target holder and targets,and owners instruction sheet and parts list.It has fired at most 50 shots,and is like new.It was purchased around 1980 and has been stored for many years.Can anyone provide an estimate of what this gun might be worth?
