UPDATE 5/6/23: I have had this authenticated by Austin Vintage Guitars and that it's all original and fits the description below. The finish was black-lighted and it has no over spray or funny business, this was done on the front/back of the body, under the pickguard, the front/back of neck and headstock. I have the letter of authenticity and can forward that to anyone interested. The owner (of Austin Vintage) who did the authentication said that anyone interested in the guitar can call him and ask about it.

All measured radii (both fretboard and fret), using a new radius gage, at the 1st and 12th frets: 7.25
Depth of neck at 1st fret: 0.861"
Depth of neck at 12th fret: 0.881"
Neck width @ Nut (measured just in front of the nut): 1.625" (ie, 1 5/8" standard Fender)
Neck width at 12th fret: 2.022"
Shape of neck: "chunky-C" with relatively big shoulders which puts it in the C/D-shape category.

1966 Fender Stratocaster, all original except for a professional re-fret with SS wire (not sure of the size of the wire but it's close to 6105). It has the most flamed maple neck I've ever seen, with an original Brazilian Rosewood fretboard. Honest wear all around, a bit of yellowing of the clear-coat, finish crazing throughout, nicks and dings, as would be expected. All the details are shown in the pictures. Case is beat, but functional. No mods, routs, repairs, over-sprays, etc. Really fantastic player with a lot of mojo. Hate to let it go.
