FOR SALE: Mobley Diaphragm for Disc Reproducer $30 ppd..OBO

[outune]

In looking through some boxes, I ran across a Mobley diaphragm for a disc reproducer.
There is a small tear-- about ⅛"-- near the edge (See last picture).
Purple paint is missing from one side and has about 80% on the other- Clearly marked "Mobley Diaphragm- Patented May ??" I can't read the rest of the patent date. About 1 ¾" in diameter.
Hopefully someone can use it $30 ppd ...OBO
