We need a trolley floor gong that matches the one in the photo. This will be used on an interurban car we are restoring at the Western Railway Museum. If you have one that your willing to let go of please let me know. We can pay or trade for it.

Here is the matching gong

Didn't Paul Class reproduce these about 20 years ago? Wonder if they might still be available.

Similar looking gongs are used on fire systems. I think you could use one of those and replicate a foot button to ring if you can't find the real thing.
