Hi E

Used a metal pointed pin and small blade.
Left a metal mark. Since it is corded I probable will not do a density/gravity test due to no skill there.

Thanks for the reply and interest.

Great idea. I have a friend that can help but it does have a cord which I would prefer not to cut. A dealer suggested that it was serpentine but he was looking at a pic. Same one suggested it was a 1960 or 70s piece.
