Is there anybody on here who can tell me the thread size of the trigger retaining bolt on this pr-war BSA breakdown pattern please, I have either damaged the thread on the bolt or in the trigger block, it looks as though i need to buy a tap and die set to facilitate the re-assembly of the trigger.
I have 0BA and 2BA bolts. the 0BA is too big and the 2BA is too small, I have heard or read that BSA used BA threaded bolts on their rifles.
