The serial Number on this one is #805707, which happens to be one of the series of numbers that Gibson, in their infinate wisdom, used in both 66 and 69, so not sure which this one is, there is no FON, not sure it makes much difference. This was my wifes guitar for many years, but she now plays gypsy guitars so it has just been sitting in the closet. It has a lovely 'ice tea' sort of sunburst, plays and sounds great. It has an updated saddle, but the original is in the pocket of the original hard case, which is pretty worn but quite functional. A bit of playing wear, but a lovely guitar with a great vintage vibe.
