Trivia , Who had Aluminum plates?

[Bdshull@AOL.COM]

Hi, Ric,

I think "Alcoa" is the clue, but I did a repair on a separated back a couple 
years ago on a Cable console with the aluminum plate just like you describe.  
Not a great piano, but I helped it survive for another few decades.

  It was silver colored and had Alcoa stamped on it.   I forgot to get the
 serial number and didn't think to try my magnetic picker upper on it.
 Does anyone know of this company used aluminum plates?  ---ric
