I am working on a Chickering Grand with the damper levers basically falling off. They are no longer attached and are loose in the piano. I was unable to find a serial number, but the piano had an Ampico player in it at one time, so I am guessing it is from around the 1920's.
1. Is anyone familiar with this era Chickering back action that they can let me know how the damper levers were attached?2. I am anticipating that I will need to drill holes in the flanges and the mounting "rail" and reattach the levers. When doing this with a replacement back action, what is the procedures for making sure that the damper levers are correctly aligned to the strings and damper guide rail.
Any other advice on this job would also be appreciated.
Someone here has the same vintage and he just sent the keys out for new keytops and bushings. It also had a player that was taken out. Serial was stenciled on a plate strut and it was 1921 built in Boston. Take pictures of what you have. Next week I will try to do the same.
If you want to find the serial number look on the top of the lyre after removing it Another place it could be is stamped into the soundboard.
You may need to tap the lyre with a rubber mallet if it uses the butterfly locking plate like Steinways have
