A.B.Chase Upright?????

[gordon stelter]

Wood blocks? What are they? Do they have a slot
between them for a small plank to act as a
"teeter-totter" as on my Knabes? Are there obvious
screw holes for trap springs, or wells for coil
springs? You just may have to figure this one out,
even if the new arrangement is "unique". Solenoids?

I have a buddy with 1,000 old pianos. I'll ask him,
and he sells parts cheap, but I doubt he remembers
what all he has.
