Another Button ID...

[Swartzie]

Another button for the experts. This was found in the same area as a flat button and a tombac. It doesn't look much like a flat button. Could it be another tombac? There are no markings on it.

Your help is much appreciated.

Brass or copper flat button. One of these days the right one will show up in the hole!
