Using the original SIT motor, the bellows unit takes less energy than the piston conversion, and I think the bellows in good shape puff more smoke. I used to offer to give folks the original bellows cloth, but it's now made of unobtainium--it was used mostly for player pianos, and no one makes it anymore! There is a substitute with man-made fabric, but it won't glue with the old Hide Glue, one has to use a modern glue--which might not be an issue with the SIT units, but I haven't yet purchased any of it, so I don't have yards of it laying about to cut off the little bit that an AF unit needs.
