I am looking for the air operated bell and the horn/whistle similar to the ones on the photo

Hi. The "horn" is actually a standard Westinghouse "trombone" 3-chime air whistle. Contact one of the larger trolley museums and if they have a spare they may sell you one. I've read somewhere where a museum actually manufactured one of these but can't remember who did.

There was a company out east that manufactured brass bells in various sizes. I'm sure one of the correspondents on RyPN can point you in the right direction regarding the bell and the air ringer mount.

Thanks!

I believe there is a "Law" that states the smaller the locomotive, the larger the horn. ;-)
