Wanted - 4" diameter spin to start electric clock like this.
Brand Unknown - It dates from 1932 and has a Pat. Pend. stamp on the back.  I am sure that it is a stock design not specific to this radio.

At this point I am trying to locate this exact clock not just make something that fills the hole.
What does it go into?  Back in 1932 a small manufacturer located in Newark, NJ named Radio Products Company built the smallest clock radio of the day...  Very few were made before the company went belly-up in the Depression. 

Alan Douglas did a great write-up in Radio Age for July 1990.  This is a picture of his set.  I have recently acquired one of the sets in fine shape except that the clock is gone...  It is a rare radio that deserves to be made whole again...  Can you help?
