Thanks!
I finally found a good photo of a bell with an air ringer!

Air driven clapper.

I want to add a bell to my Alco RS-3, similar to the one in this photo:
As you can see, it's mounted differently than on a steam loco. Can anyone tell me how these were set up -- Did the bell swing from side to side? Or was it held in place and only the clapper was moved?
