I'm restoring a 50s vintage EICO 720 transmitter. I'm in need of a 50 k
potentiometer rated at 4 watts (or above) that is NOT wirewound.

The old part looks like a thin ribbon-like piece of resisitive material bent
into a circle and placed inside the pot case. The spring loaded center
contact appears to be in good shape, but the ribbon is fractured
(microscopically) in two locations along its length.

I have been unable to find a replacement for this part at any of the large
parts supply houses.

Is there any hint of who the original maker might have been?

What's the overall diameter of the pot?
