A 44 Button Crane Duet

Here is its full specification:

  • Seven fold plain black goatskin bellows.
  • Black walnut burr veneer with black Rocklite Ebano border inlay.
  • Ebonized beech handrails with integral strap fixings.

  • Standard scale reeds on the left hand, long scale on the right hand.
  • Sycamore radial tapered reed pans.
  • Sycamore action boards.
  • Brass sheet riveted action levers.
  • 3/16″ nickel silver capped buttons with acetal cores.
