Saw this at an estate sale. It was pretty heavy. Couldn't tell what was written on it.

Any idea on the diameter?

Any idea on the diameter?

I'm guessing like 5-6 inches across.

Sorry, no clue but just wait a little while and someone will be along to answer your question.

Weight and diameter will be the tell tell.

Unfortunately it was sold when I got back there. Still wondering what it says.
