In response to Philip Jamison's problem with bent Simplex valve caps:
I have about 14,000 of these I had specially made.  I will be happy
to send you 100 for your check for $10.00 which includes postage.

These were made to the specs of the late Simplex Recordo players that
used a larger hole than earlier upright systems.  They are made from
fiber, not metal, so they can never rust or corrode.  I have used
them for several years and they work very well.
