HP 87 Keyboard parts (plungers)...

[Clay Archer]

I recently acquired an HP 87 that I was able to repair, all except for a
few sticking keys.   From digging through the archives at this site and
the HP-80 Series sites it seems the only way people have found to fix
these is to cannibalize the plungers from other similar keyboards.   Has
anyone figured out a way to repair these cracked key plungers yet?  I
have tried a few things like gluing and wrapping and melting, etc, with
little success.  Does anyone know a source for these plungers?  The HP
part number 1535-4043 still comes up on HP parts site with no stock.
