Used wippen/whippen (techs still discuss the proper spelling...) and sticker assembly for old upright player piano (note the regulating screw and button on front for contact with the player mechanism finger).  These were pulled from a Gulbransen but will fit other players with similar dimensions.  See pics for measurements.

Choose spoon orientation: left, right or none - see pics.  This is as they would be seen while seated at the piano, and the reverse of how you would see them when viewing the action from the back.

I've been a tech 30+ years and serviced and restored many pianos.  If you have questions before or after your purchase I'm glad to help. My contact info is included with each purchase and you can also reach me through eBay.
