Doug, I see you are working on a FW that has been worked on before looking at the screw on the coupler.
As they say, a picture is worth a thousand words.

You can call the parts what you like, but the part that you call a cam is really a lifter.



King, if you think an L.C. Smith is hard to cock when fired, try cocking any English or Spanish gun with Southgate ejectors, you really do have to break it open over your knee.
