Maybe you should look at it in person before you buy it.
Just scouting, I see:
. Hardware-store neck repair with GOKW adhesive
. Resulting in potentially questionable neck angle which given the hinky neck-set could be a bear to repair
. And even if they did it "to original spec" old Kays are famous for their shallow neck angle in any event
. Lamination peel on the edge and pretty far up the center-seam
. Bridge is bent
. No case
. I don't know if the finish is factory or re-do but others will doubtless chime in.
Assuming you're comfortable with the neck angle and that the neck is soundly attached, your minimum acceptable setup will be strings, bridge and fingerboard-plane, at several hundred dollars out the door. Add another 1-2 hours for lamination repair. A case is required even for a backup.
After that, you could opt for a new end-pin and/or bridge adjusters. If it's like every other Kay it would sound tons better with a neck re-set, except here that's a double-price job because of the 'screw-and-glue' job that Elmer did last time.
After all that you might decide to find a different backup. Or you could buy this and let it sit until. Or you could buy it and put money in. But that's really not something you want to decide by internet.
Good luck and let everybody know!
