I came across a little black "cube" about and inch thick and 1 x 1.25 inches

tinned leads. The top is stenciled PH-7. (Philbrick?) Because it's somewhat
conical and rounded at the top it looks like it might have been cast in an
old style ice cube tray. Google doesn't help so I wonder if anyone out
there has an idea?

It's not in my 1972 Philbrick or 1974 Burr-Brown catalogues. All the Philbrick
stuff starts with P but not PH.
