The chance to pick up an unrestored not playable but complete Aeolian
Hammond model BA, circa 1938, organ has come up.  I would appreciate
any general advice on these as to difficulty( or impossibility) of
restoration, i.e., parts and wiring diagram availability, and what
they are like when restored, do they sound good, did they work well
originally, and any recent prices for units is unrestored shape.
Is the player unit part pneumatic on these?

Does anyone have a working Aeolian Hammond player organ for sale?
If so please send details.

Thanks, John McClure
