Thanks for the input. What is a magneto bell? I did a quick search & a lot of phone photos came up.I did some searching too! And I don't think it is part of a phone. here are 2 links: Sweet's Architectural Catalog File - Google Books Canton - George T. Comeau - Google Books I think that it might be an adjuster for a magneto bell. But I couldn't find the one that was made by that co. I think it is still unsolved. just my opinion.
Darn .. and here I was thinking it was part of a Perfex Vibrating Ignition Coil.
kind of hard to see but it does look like it.Maybe something like this: Perfex Coil Spark Plug Gas Engine Primary Vibrator
