Mystery item in Lyon and Healy Baby Grand

[John Dutton]

Hubble makes electrical jacks and plugs for all sorts of industrial
applications especially for 30amp and 50 amp 110/220 jobs.  Most of these
are in a twist lock configuration.  RV's also utilize Hubble connectors.  I
use them quite a bit in sound pa/reinforcement work for power cords etc.
When I worked down in San Diego we used them for commercial/university
installations as well.  They are readily available at Home Despot.  Your
wiring looks like old school cloth wrapped 14g.  I don't know what they
would be used for in a piano-especially four of them.

Hello list,

 

Can anybody tell me what this item is in a Lyon and Healy baby grand?  It
looks kinda like an electrical outlet, but it's not.  This piano has four of
these: two inside the rim like the one in the pic, and two on the rim on the
UNDERSIDE of the piano.  There is one two-lead electrical wire running in
series through all four of them, but no tag lead hanging off from either end
that would suggest hooking them up to something else.  Weird.  Anybody know?
