I am having trouble getting the stock bolt out of my 1906 BSA LJ pat.

Seems to be well and truly seized. Already broken a couple of cheap screw drivers and one good one trying to get it out.

Weird thing is, the stock and trigger block are loose, as in I can wobble them about and it looks like the stock bolt can turn slightly inside the trigger block (the head does not turn in the stock just the threaded end in the trigger block). But that is it.

Tried soaking it in WD40 but it is still stuck.

The stock had a small crack near the front end when I got it and after trying to force the bolt, it looks like the split is getting larger and I really dont want to break the thing.

Anyone any ideas?

Thank you,
