Hi Baz,

Lovely condition gun from the very first batch of guns made by BSA, for sale under their own label. The cylinder should be marked The BSA Air Rifle (Lincoln Jeffries Patent).

It has the uncommon long tang trigger guard, which were cast, and fairly brittle. The tang for the your stock , is straight, however the tang for the Pistol grip (known as the Pistolhand stock) was curved, and very time consuming to fit. Many breakages occured at the factory, so the long tang trigger guards were quickly phased out.
John Knibbs gives the dates of manufacture between Sept and Dec 1905, and it would have sold straight away , such was the demand for these revolutionary guns.
The rifle has a later rear sight fitted from a 1920's gun - that stands out a bit for the purist collector.

Early guns like this had a narrow parallel hole in the deep loading tap, so will need a pellet pusher to properly seat the pellets in the breach. Value wise, I would say around £220- £275 somewhere around there, but that is only my opinion.

Nice rifle that doesnt look like its had a lot of use.
