3D3DPromethium luminous compass.
This is a beautiful solid brass compass of a design that dates back to WWI, but this one was most likely made in the 1950s or 1960s, assuming it does in fact, as claimed, contain promethium luminous paint on the dial. I hope it does because otherwise I don't have any example of a promethium luminous object.
