These bushings do not have the bronze set screws.

I got the right side bushing off with much effort but did succeed. It was very clean as the prior owner had dunked all but the whole gun is grease.

The left side is giving me fits. I have used all kinds of penetrating oil, a properly fitted and slotted screw driver and copious amounts of torque.

There is no rusting on this gun so I would have a hard time believing this is the only rusted up part.

Any thoughts on removal?

I obviously do not want to destroy the bushing if at all possible.

BTW just a real nice O grade gun. No high grade LC Smiths were hurt or damaged in this episode of Tinkering with ole man LC.

Many thanks
