Hi Everyone, my first post...

A few months ago I purchased a 1920s (?) Chickering 9-foot grand. My first love is playing (Debussy, Ravel, Brahms..) but I am also refinishing the case and working on the action. For now, I have two questions...
1) I cannot find a serial number anywhere on this instrument, and I have searched inside and out. Case number reads 1050 but that is the only number I can find. I am guessing at the date based on pictures of others online.
2) The legs are missing the square brass ferrules, and it is evident that the piano once had them. Can anyone help? Size is: height - 1 3/4", top - 2 3/4", and bottom - 2 1/2".

Thanks so much!
Dave
