Here's a before and after on a mk2 BSA Airsporter that I acquired and was quite rusty. You can make the rifle finish 100% better by getting some fine wire wool, soak it in light oil (3 in 1) then go to work rubbing it!! If it does have the 'B' prefix then it was made in 1936. The Break barrel he goes on to say that if it doesn't have a letter 'B' before the number then your rifle was made in 1935.

The one he shows in the book is serial number 29706 and he reckons it was made in 1909/10 so yours should be earlier. Your Improved model D was produced between 19 according to Dennis Hiller in his book, collectors Guide to Air Rifles and so was bought before even the First world war!!!. It sounds like you dropped on two nice old guns If anyone can help I would be very grateful as I would really like to get them up and running and shoot a few targets at some time. Again plenty of rust about and the front and rear sights are both missing but it cocks and fires a pellet.The person I bought them from said his Father bought them before the 2nd World War. I can find no writing on the gun except for the serial number but it has a pistol grip stock with BSA stamped into the grip, lower down the stock is stamped with the BSA logo of 3 stacked rifles. Serial number 6631 and is a break barrel rifle in. The gun cocks and fires a pellet, the caliber is. The rear sight is in situ but at sometime in the past the adjusting screw and top of the sight has been replaced with a small piece of aluminium with a v filed into it, one of the screws holding the trigger guard is missing along with the large screw underneath the loading tap on the left as you are holding it. The gun has traces of rust all over although you can see the blueing showing through, a small split at the front of the stock about 2" long and the stock is slightly loose.


It also says LOAD on the pellet aperture. Stamped on the top of the cylinder is The BSA Air Rifle (improved model D), The Birmingham Small Arms Company Limited, Sole Manufacturers. Serial number 15346 has a pull down lever to cock it which says underneath Lincoln Jeffries Patent. I can't post pictures as I don't know how but I will do my best to describe them. I know nothing about BSA guns apart from what I have picked up on the Forum so would be very greatful if anyone can help me date them and give a bit of info. All my life I have owned collected and shot Webley air pistols and rifles but just before Christmas I was wandering around our local car boot sale when I came across 2 old BSA air rifles which look as though they have been in someone's garage for the last 50 or so years but the price was right as they say so I bought them both.
