It was a mess in a box next to my workbench. It had been there for some time. It was so bad I tried fine steel wool and brasso as I was not sure it was bakelite....it is ;D It cleaned up to look like new, but it appears to be missing some parts. It looks European to me, but what do I know....thanks....Doug
