Rebuilding SA

[Tallball]

Maybe I'm mistaken, but I think H&R made a 22 caliber DA revolver that looked like a SA revolver. IIRC, the cylinder didn't swing out, so it had an ejector rod and loading gate and so forth. But the trigger could be fired DA. Someone with a better memory will no doubt correct me or add details.

Note: I just saw one on Gunbroker. It was a Model 650.
