I am hoping someone can answer a question for me regarding cylinder design variations. Some 5-shot .32 S&W Iver Johnson top-break cylinders have a "long" machined cut for lockup without a defined "stop" at the deeper end. Others have a much shorter ramp with a defined perpendicular notch.
I have seen both examples on early and late versions of these revolvers, both Safety Hammer and Hammerless. I have swapped some cylinders around and they seem to be quite interchangeable. Is there any significance to the design differences?
I would appreciate any information.
