Have a question and hope someone can help. I believe this is a CD 132.2 because the dimensions are 3 by 3 7/8 and looks like it is. The question I have is what is it? There is a large round indention in the top with a backward 14 imprinted in it. inside at the top of the pin hole is a glass button protruding down and the top of the plunger (pin hole) appears to be 4 sided. and the hole is oversized for normal pin. Is this an unembossed variation? Any help? Thanks Don
