I think this is my guitar and was added over from the old spreadsheet. My SN is 70959 and is a 1964 6192 with some pretty interesting differences from the usual. For starters it is the thin body, it also has the flip up mute and back pad. It also has a solid spruce (not laminated) top with ridiculous number of growth rings per inch. It is 100% original. The fact that it is a 1964 production is confirmed by the stampings on the tone and volume control pots. Because of the spruce top, thin body, mute and back pad, it is possible this was a custom made piece. It is currently needing some work on the electrics since there is some scratchiness in the output.
