Here we have a 1958 Silvertone 24 Kay Built Jumbo in good condition. The serial number is L580 8105. The fretboard is rosewood with mother of pearl inlays. The scale is 25 3/4" and there are 19 frets. We have reset the neck and the original bridge has been replaced with a rosewood bridge with a drop in bone saddle, the nut has also been replaced with new bone. The original frets have plenty of life left and the guitar still has its original kluson deluxe tuners.
