Music Master Horn Rings-Different Sizes??

[Lee]

Pictured are: Music Master Horn Ring from an Edison Triumph (smaller shiny example) and another Music Master(?) Horn Ring. Is the larger ring for an Opera? The corroded ring doesn't show any of the prongs that I am used to seeing. I've never had an Opera so please forgive me if the answer is obvious. I bought this ring to use on a Triumph but as far as I can tell, I can't use it.

Thanks!

Hi Lee,
The larger ring is from a wooden Music Master horn used on a radio.

Ah....ok, thank you. Greatly appreciate the info! I'm a little embarrassed that possibility never occurred to me. Well, I guess I'll see if any of the guys in the Radio Groups on Facebook can use a Radio Music Master Ring! Many thanks, Lee
