I have recently acquired a mostly fair condition post war senior where the frame has been violated at the rear plug
A hole has been drilled through left to right to pin the rear plug in place (eek) with a spring pin...and its been done in such a way that the plug isnt sitting flush to the frame.

Its a pity as the overall condition isnt too bad (a few scuffs and such as you would expect) and the gun operates fine if you are brave enough to have the bodge in front of your face
I’ll have a look at the plug thread in the frame and see whats prompted this butchery but thought I’d see if there was a good frame available in case the current one is beyond safe/discrete repair.
Anything out there?
