Hi all, We are restoring a 1920s Anguera piano with a Welte Mignon
system. We are working on the drawer (which was a mess), having trouble
adjusting the collars on the re-reroll/replay pneumatic so they work
properly. It's the one and only thing we never took pictures of and
it being an incredibly complicated linkage design is fogging our eyes.

Does anyone have any words of help on this, or if possible, pictures
of that pneumatic assembly? Any help would be greatly appreciated.
Thanks so much!
