With the Guild ' white oval label inside the sound-hole with Model "F-412 Bld" and the serial number "91264" written in pencil. All hardware gold-plated. This custom ordered and now quite rare twelve-string guitar is in exceptionally fine (9.00) condition with a little bit of playing wear on the treble edge of the soundhole, some light checking and just a few insignificant surface marks on the top and on the back of the neck. Housed in the original Guild black five-latch hardshell case with blue plush lining (9.00).
"On the higher-end, Guild introduced the 12-string versions of the F-50 and the F-50R, called the F-412 and the F-512 respectively, both available by "special order" only. The '69 catalog shows a picture of the F-412, but not of the F-512. It does however mention "the customized elegance of inlaid mother-of-pearl figures on the fingerboard". Some earlier F-512's indeed have different fingerboard inlays. You will find similar inlays on many "special order" instruments from the late '60s and early '70s as well as the Custom F-612 that was introduced in 1972." (Hans Moust. The Guild Guitar Book, p. 130).
