It has the "Cotton Music" fretboard inlays formerly used on the 6 series (Maple back and sides). Def a Jumbo.
If so it would be Taylor's fine approximation of a Gibson or Guild Jumbo...
Hard to tell with the dark sunburst, but the butt appears it may be flamed maple.
Probably a 615 sunburst.
Maybe Taylor has some info on their byzantine website. Good luck finding the info if it exists. Hahaha
Any other sleuths lurking here???
