Need a detailed description of all markings and features.
BSA cadets were made between 1946-1959
The BSA Mercury was made between 1972-1980
BSA actually stands for "Birmingham (UK) Small Arms" they first made guns; hence the 3 crossed rifles on the badge. Yamaha, who first made pianoes, copied the idea putting 3 crossed tuning forks on their badge.
BSA made several different air rifles. Unfortunately you did not state the model number and that is critical. You could try to contact BSA and ask them. see the link below.
Probably about 2007 - Gold SR.
I think that 5,000,000,000 motorcycles have been made. The question is how many of the flagship high horsepower 1968 BSA spitfires were made. A few thousand for that year my estimate. Maybe less.
Birmingham Small Arms Co made motorcycles
About 4000

The BSA Airsporter with the serial number GD34696 was produced in 1965. The serial numbers for BSA Airsporters follow a specific dating system, and the "GD" prefix indicates that it was manufactured during that year. If you need more precise details, you may want to consult a BSA Airsporter reference guide or enthusiast forum for confirmation.
