WYSI - thanks so much for the thread references.

Bill D - they have likely NOT been played since they were recorded, and the brand names seem to vary, though a good number of them are Sony.

Danesis - what does that mean, to "spool them from end to end"?

GUEST ocd - thanks for the screws idea. Might some simple Elmer's glue work to glue the contact pad back onto the metal lever that holds it?

Thanks to all...
