With all due respect, we both agree as you stated;
"The car is a 67 Shelby and has a vin tag to document that."
So day one in 1967 and today 2019, the legal paper work states it is a 1967 Ford or Shelby convertible.
Today, in what ever state it is legally registered in, it is a 1967 Ford or Shelby convertible model.
Comprehend your stance on the lack of photos. But why are photos needed when you have the subject in front of you, Shelby, topless and a 1967 vin.
I believe it to be one of one. Its evolution (like all Shelbys) went from a 1967 mustang convertible. Then became a 1967 Shelby convertible, that was eventually converted to 1968 Shelby trim.
That's is my opinion.
i think they may have made one 1967 convertible

Yes and maybe The car is a 67 Shelby and has a vin tag to document that. The million dollar question is whether it was ever built to look like a 67 Shelby . Unfortunately unlike all of the pictures of obscure ,proto type cars like Little Red ,The Green Hornet, etc. there are no pictures of the 67 Shelby convertible in anything but numerous pictures (100's?) pictures of it in 1968 Shelby trim. It is the red 68 convertible on the color dealer brochure . We do know that for a fact . It was also painted white for other advertising pictures. It is more then a little strange that if it was meant to be in 67 Shelby trim that there is no picture record of it like other obscure Shelby cars. Shelby didn't miss a opportunity to photograph just about every unusual or obscure car that they made. You would think that something as out of the ordinary as a 67 Shelby convertible that there would be pictures of it like so many other Shelby cars . That is if it ever was in 67 Shelby trim . The jury is still out on if it was ever in 67 Shelby trim back in the day . The owner wants to believe that it was . I don't blame him. The evidence or the lack of evidence is leaning towards it being the convertible engineering car for 68 production. Maybe some day definitive evidence will confirm that for a short time it was in 67 Shelby trim. It is a cool and historic car regardless.The current owner chose to first restore it as it was in the 68 Shelby color brochure car trim and then decided later to re restore the car in 67 Shelby trim which it is currently in. Too bad Shelby didn't offer a convertible in the 67 model year because it would have been cool.
