Have a old top break revolver from SW, made between 1918 and 1919, this one has a hammer. My problem is that the hammer does not return after firing, the firing pin stays thru the frame hole, but just does this on 4 of the 5 cylinders. Revolver has been cleaned real good but has not been taken apart, just the side plate off for cleaning. Hoping to here from someone that works on these old revolvers. This one is in great shape except for this trouble. Thanks

I think the rebounding hammer is a function of both the trigger and the hammer plus the associated springs. Make sure there are no burrs on the firing pin/hammer nose or the slot in the frame. If it was dry fired excessively, someone might have "flowed" the metal back in place in the frame leaving a burr in the trough which could hang up the hammer.
sometimes it hangs on all 5. With hammer spring out hammer moves freely in and out, so no burrs or such.
It's hard to tell from your description? But I would check to see if the hand, and the the machined hole it travels in are in good shape. Not broken or binding. Also check out the machined ratchet surfaces on the back of the extractor star. For the same. To see if they are binding up on the hand. As the cylinder is moved either by the hammer, or the trigger being actuated.
