For trade as collected:

- Metal stack with original electric primaries. Valves appear to be
  all there.

- Pneumatics: only 6, but of all three sizes.  Original decks show
  where different sizes were. Poppets included.

- Extremely rare, spare parts.

Will trade for a Duo-Art stack from the 1930s which uses the tiny
valves usually associated with accordion pneumatics (usually these
stacks were in Stroud pianos) and a 17-inch Duo-Art rotary pump.
