Does anyone have an exploded diagram for the BSA boxlock - simple double triggers, extractors? I picked up one in tough condition, refinished/recheckered the stock & touched up the metal. This is a bottom of the line gun, but it's still light & swings well, although the firing pins do drag on the fired primers.

The result was a pretty nice gun, but now one of the locks won't cock. So before I start taking it apart, anything special about these I should know?
Regards, Ron

Try John Knibbs via this link. He holds all the BSA records and may have some spares as the older Birmingham made BSA shotgun was machine made. Lagopus.....

This is an old English BSA boxlock, made in Birmingham.

The link is for new BSA stuff.

This is an old one, pretty obscure so I guess I'm going to have to do exploratory surgery on the old girl.

Yes, but John Knibbs who owns BSA still has the historical records and some spare parts if you contact him on that link he should be able to help you. Lagopus.....

I have a B.S.A.shotgun catalogue that shows a cross sectional view of the action.They are very similar in design to the Anson and Deeley action found on most boxlock guns.Recommend that you have a competent gunsmith provide assistance with inspection and repair of the action. B.S.A. guns were inexpensive, but they were made from the best available materials. The Jessops fluid compressed steel, chopper lump barrels are joined by a vertical dovetail [As used on the Winchester model 21]. The result is a very strong gun, perhaps a little heavy but normally a very reliable.

I have a similar BSA. One of the first doubles I purchased. I found it in a pawnshop in Winslow, AZ. I paid $75.... grin

It had similar problems in that it was missing a trigger and some wood at the head of the stock. I asked questions here and when I get to my home computer I'll post the compilation of information that the kind folks here supplied.

It has been my back-up and rainy day gun on many hunts.

Thought I'd post what finally happened with the BSA.

Seemed like a pretty standard box lock, so off came the stck and the floor plate. Nothing obviously broken. Took out the sear springs, punched over the pin holding the sears, & removed the sears.

Turns out there was a little disk of metal holding the right sear out so it wouldn't catch the hammer. A pierced primer must have blown the disk back into the action, where it rattled around until it landed between the hammer & sear. For good measure, I blew out the action with carb cleaner and tri-flow, reassembled the gun, & it's good as new.

Regards,
Ron
