I've had a Reed 404R for about 30 years and just found out that it has a swiveling rear jaw

but can't for the life of me figure out how to remove the pin. Any suggestions on how to do this without destroying the pin?
SteveL, don't feel bad about not knowing about the swivel jaw. A lot of people don't know what that is on there for.---I bought the nice, 6'', 124 lb.,
Rock Island #54 off of a mechanic who thought that you pulled the pin to oil the slide.---He had two and would sell either one.---The other was a smaller
Charles Parker swivel jaw, and not in as good a shape, so I chose the
Rock.---$150.00 and 100 miles, round trip, it found a new home.---I wanted both but he wouldn't sell both.---I can't remember the # on the Parker.---But I didn't try to deceive, I told him what the swivel jaw was for, but he was sure he was right.---Who am I to argue.
Notice the close tolerances between the swivel jaw and the body.---Minus the paint and the crud, it's almost as precise as the
Reeds.---Now that's saying something.
