While it's true that the first clay models were sculpted by hand, this one lacks the finished "look" of something like this.

If it really is a GM produced concept model, I agree with Moose: it looks pretty rough... perhaps a first gen paradigm? Perhaps not a GM effort at all.

It does have some resemblance to a 1954 Motorama offering of the Corvair, complete with fiberglass body.

GM pumped a lot of promotion money into that contest for a dozen years, or so. This model looks to be one of those.

You saved me the effort of posting, thanks.

Could it be a Tucker?

BTW, has anyone else experienced shut down of IE when using the "read whole article" links? This happens repeatedly and only with these Hemmings Blogs.

Yes, Google Aw-Snap and you will find many such problems with many different platforms, there are several apps claimimg ownership but there doesnt seem to be any fixes yet.

Remember the 53 & 54 corvette?

53 Corvette

Any Aussie will instantly recognise the second clay as the FX or 48125 Holden of 1948. It was designed by the Yanks at GM Detroit but aside from 3 prototypes built in Michigan was later built at various GM Holdens plants around Australia. In 53 it became the fabled FJ Holden, our much loved "Humpy". When I first met my wife 15 years ago she was driving a restored two tone green 56 FJ. I thought that's the girl and grill for me.
