Didn't the DD's get G-shields?
This one's got a Chesterfield.
Also the the DD's got fretboard markers, this one's bare.
I'm willing to bet that since he was an endorser, it was an actual custom build.
Aha!!
A google search yields this comment:
"Towner had his first F-212, right in time - after Paul Winter Consort - to join Weather Report for "The Moor" on "I sing the Body Electric".
Shortly after followed
at least two custom-made at Guild's workshop: a Florentine cutaway F-212 and an abalone-less fretboard F-512: the first mahogany bodied and the second in Brazilian Rosewood, both with flat, classical-like 52 mm at nut fretboards as per Ralph's wishes, needing the same room he was used to while playing his classical guitar."

(Apparently he ordered the guitar before he was an endorser, though!)
By the way thank you so much for the post.
Towner's been a hero of mine ever since my best buddy introduced me to him, and Oregon, back in the late '70's.
Gonna send him the link.
EDIT: a-ha, I see, as happens sometimes, somebody else was posting while I was still composing, but hey, nuthin' wrong with a little collaboration and corroboration, right?
