What tool to adjust Lefever ball and socket joint?

[Big Friend Ten (BFT)]

Brad,

The gun is a Lefever D Grade 10 gauge that you'll enjoy seeing.

Thanks!

Mark, is it a screw slot or a two hole spanner? Many years ago, I made a punch type tool to break them loose, but I had one that just wouldn't break. Brownell sells an adjustable spanner that probably works better than the spanners I have made.

Wow! This sounds like a real nice Lefever. A seldom seen D grade in a 10! Sweet!

If you have pictures, please share.
