WANTED: Key for an Edison Amberola A1

[hexaphone]

I believe it uses one of the variations of the Dolphin key. I have read where the one that works is 2 ⅜" (shorter) versus the longer 2 ½". I don't know if one or both work.
Anyone who knows, please feel free to chime in as I'd like to find the correct one to go with this machine.

PM or email ronbrink@aol.com with any information, offers, etc. I will be attending the Union show.

Thanks
Ron
