I am not quite sure I got the name right, but this little pre-war BSA came home with me last week
It wasn't working quite right, and it turns out the spring is broken in several pieces, the piston washer is damaged, and the washer screw is damaged. The was a few lead BB's embedded in the washer, the previous owner tells me he has been shooting steel BB's too..

So, I'm looking for a spring, a washer, and a washer screw. Preferably an original spring, as those BSA markings at the spring ends feel important

If anyone on here has some of these parts, and are willing to sell them to me in Norway, or know of any place the can be bought, I would be grateful!
