I totally agree.

I would never have thought of that!

Now I have to find out what it produces; maybe the outer ring for a planetary?

Thank You NICK

Are you sure it is not bronze? Bronze gears are very common in pre-war cars. Riley's use them for the speedo drive, magneto and coil ignition and oil pump drives at the very least. I know other cars use them too.
