Just a bit off topic from pre-war TRK's but from the same RCA family.

These pianos were exibited at the Worlds Fair with the TRK's. They were a collaboration between RCA and Story & Clark (piano makers) to produce the first electronic piano with electronic pickups. Read the Bay listing for details or search it for more info.
And Story & Clark made their soundboards in my hometown. How could they abandon them for tubes? I am crushed.
The Vassos TRK styling is spectacular. Makes my TRK look plain. And makes my TRK look cheap.
