Re: Identifying My Kay Mando
FWIW, my cosmetically-similar '63 Kay guitar has (or had, it's long since worn off) the identical logo on its white, screwed-on pickguard. By that point, the headstock logo was also a white painted-on affair, rather than pressed metal.
For the last 30 years it's been strung w/ electric 10's (to keep it from collapsing in any further) and has circulated thru 5 or 6 family & friends' kids that have learned to play on it. It taught me how to replace tuners, make a new nut, and re-glue the bridge & bridge plate, and I look forward to re-setting the neck when I get it back. I would re-fret but have grown accustomed to the "suspension bridge" geometry that's worn in both under and between the strings!
