It is a Lyon and Healy Style 20 with serial number 759, likely built between 1905 and 1909. My grandfather bought it used for my mother in the early 40’s. The neck was replaced about 20 years ago. I just found out that when that work was done this issue was not addressed because my mother wasn’t playing much anymore.
There is also an issue with the sound board being pushed a bit forward on one side and on the backside it is cracked a bit and pulling away from the center sound holes.
Still sounds beautiful even with incredibly old strings.
Just trying to determine if it is worth the investment of regulating and getting new strings.
