There are a number of places that an individual can find BSA rifle scopes. Some of the places you may want to try include BSA Optics and Air Rifle Scopes.
The BSA Mercury was made between 1972-1980
BSA cadets were made between 1946-1959
The BSA Scorpion was made Between 1973 & 1993 in two variations. In order to give an estimate of value I need to know the current condition of the pistol. Poor to Excellent.
