I ended up buying the accordion from Byron.
Most of the issues were created by someone that tried to "fix" the accordion.
They put some of the flappers back on upside down and tried to use double stick foam tape as felt pads.
I cleaned up the keyboard, repaired the broken flappers, added new pads and leather and adjusted the flappers and keyboard spring tension.
The valves on the bass side are also old and dried up.
The reeds are out of tune and the reed gaps are off,
I'll start on the inside next week.
