I have recently bought a Senior, batch number 860, 1860 under the grip (an approximate date would be nice) and need a couple of parts.

The barrel bolt is missing the locking screw, just knowing the thread and size would help with that. It also looks like the breech seal is past it’s best. Should I try neatsfoot oil on it, or replace it with a leather or rubber one? Ideas and links would be very much appreciated.

I stripped the gun today, cleaned out the oil and applied a little Bum-Slide in it’s place. The boiiing has gone along with a lot of the smoke. Power has risen from 250 to 285fps, I’m sure I can crack 300fps with a better seal!

Lastly, the barrel has some wobble at the front. Has anyone successfully shimmed this?
