My father, who past away in 1985, had a guitar in an old hardcase that I occasionally thought of. Yesterday, I went by my mother's and picked it out of a closet and took it home. I hadn't openned that case in at least 20 years that I can recall. It turns out in a few hours, I had ID'd it as a 1937 "archtop" Gibson L-12 accoustic Jazz guitar. My father toured with a Jazz band before he enlisted just before WW2.
Also, as I had recalled it is damaged. There is about a 7" crack from the top "F-hole" to the top of the body. Otherwise it is in very good condition but for the normal lacquer crazing, which is not bad at all.
Questions:
What should I do about repairing it? (how much repair? Refinish the entire top? No refinish, just leave the crack line after glueing?)
Who should do it?
