In holding it next to my transitone head, it is a very close match however a bit lighter in shade.
Next to a regular brown house radio rosette, it appears much darker and almost black.

Now you have me wondering if not a auto transitone, where would Philco ever used a key knob like this?
Hotel service comes to mind where it would be inserted in the room radio if additional fee was paid?

Any other Ideas?
