We have recently located and purchased a lovely late 1920's Bechstein
Green Welte.  We have 50 rolls including an original test roll.  Also,
in our stable we have a red [T-100 roll] Welte-Mignon Vorsetzer in a
million pieces.  We have 44 rolls with this including an original test
roll.  Finally, we have a lovely Welte-Mignon Licensee Vorsetzer which
is pushed up to our 9-foot concert grand piano.

Is there any way of making the green roll or Licensee roll machines
able to play the red Welte rolls?
