I met a gentleman at an art show, we got to talking & he was
remembering when he was a college student, he took a metal working
class.
Back in the late 60’s early 70’s. He called me today & said that he
looked thru his old boxes & he found materials that he had stored
away.
In the box was a sheet of metal which he says is sterling silver. He
indicated that on the sheet, written in ink is the following: RNBBB
Plate.
He is not near me so I have no way to verify what the material is -
can anyone help me identify whether this is sterling based on the
RNBBB.
