Lines look like an early Barracuda.

Looks more like an AMX.

The wheelcovers are early Barracuda.

AMC used caps like that also.

At that point in the model, it sure reeks of 70's B body...

Ah yes, I remember those days building those clay models! Maddening! Simply maddening!

Check out those highwaters!

That roof line does look like the AMX 70 model year?

back side of an AMX.

Not an official AMX model. I did a search, and none of them look like that. I'm guessing a foreign marque?

One more thing, that pic looks a lot like a school. Maybe a design school styling exercise?

The body lines look much later than 1964 to me. They remind me of the Challenger clay models I have seen.

it looks like the passenger side, rear is already finished. Behind the man's legs.

Did I miss something? What indicates this photo is from 1964? Maybe it's a popular photo I don't know about...

The photo is from a Chrysler web site. Here is the lable that goes with it: Fellow clay-model makers John Herlitz (left) and Jack Avileto (right) work with Al on a 1964 show car.

not the 300-X...

That is actually a styling exercise from 1967 called the Barracuda SX, according to the book: Chrysler concept cars 1940-1970.

Must be an exercise because it's not the SX show car...

My 1964 sketch for the 1967 Barracuda Project. It was deceided to have a smaller backlite than that on the previous Barracuda. I designed the "hatchback" model for 1967 and revised the front end and hood. I had always liked "real" eggcrate grilles, but high cost kept them out of most car designs. I noticed the aluminum eggcrate grilles on the overhead flourescent lights; they were very thin so they wouldn't block much cooling air, and must be cheap. I obtained some of the eggcrate and had it trimmed to fit the Barracuda's grille. It passed the tests for exterior use, and was used in the production cars.
