Rivets for ashtray and original finish of the metal Options

[doug_b_928]

Has anyone restored their ashtray? Disassembly looks to be very easy. The big problem is what appear to be very unique rivets.

First, there are the rivets below that hold the rotating piece of chrome in place. They do not rotate but are precisely sized to allow the chrome piece to rotate smoothly on them without any slop or squeaking. They look like they might be brass.





And these rivets hold the plastic (to which the front piece and other chrome piece attach with two screws) onto the steel. They look like pop rivets on the bottom but they are very flush on the top side of the ashtray (barely visible with the corrosion; also appear to be brass). I guess that they could be replicated by grinding down the back side of the pop rivet a bit...







Does anyone know where these rivets can be purchased?

Also, the metal of the ashtray almost looks to be just unfinished pot metal? Was there some kind of finish on it?

Appears to me to just be zinc
