Hondo 44 and sureshotbob,

The question was regarding S&W revolvers, there was never a S&W top break in .32 S&W Long.

There may be some .32 S&W Long top break H&Rs from the 1950-60s, hardly the period usually associated with this frame style, and far stronger than the early black powder era guns.

Early, at least some, H&R and I.J. revolvers chambered and marked for .32 S&W were bored straight through and will chamber the .32 S&W Long, but that doesn't mean they should be used with that cartridge.

If you can come up with a photo of any pre-1940 top break revolver of any make which is marked on the barrel for .32 S&W and S&W Long, I would be interested in seeing it, please post! Otherwise we will have to assume you are merely speaking of early guns that will chamber either, not intended bu the manufacturer to be used with both cartridges.
