There was a company, forget their name, that used to package simple
modules like you describe. Like audio amps and the like. The package
was just a clear plastic with a piece of paper closing the top. Seems
like the pins were stuck in a square of styrofoam.

Looking closely at it I can see what might be TO-3 edges thru the dark epoxy

I came across a little black "cube" about and inch thick and 1 x 1.25
inches
on the sides. The top is pitch black and the bottom is gray with four
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?
tnx
