I have here a Pedersoli 1858 B/P revolver with a Westlake stainless Nitro converted cylinder. Five of the 6 firing pins in the cylinder appear to be stuck in their bushings and the only one that moves doesn't move freely so does anyone know how to get the pins out please so I can give it all a good clean ? It looks like the pin bushings are pressed in so I'm guessing one would have to carefully push them out with a small brass drift by tapping the actual pin from the front, I can't see another way of doing it. Also, doe anyone know if these pins should be spring loaded or not as the one that moves is not. Thanks...
