FYI, I do have this model... somewhere, in one of several "dishpack" cartoons I've got stored, holding all my various unbuilt kits. But as I recall, there was nothing remotely complex about the construction of this kit... nor was the "paint scheme" very useful. So, except for "collector" value, I can't see the need for this.
By the way, I'm presuming you're talking about the 9" figure, not the 18" one. The 18" "kit" isn't technically a "kit" at all... as I actually own the original release of this, which was sold as an "action figure" back in 1979. It was, at the time, the coolest "toy" I'd ever had. Of course, I was thirteen at the time, soo.... It had glow-paint in the recesses of the head, under the smoke-grey transparent "head skin." and it had a little device at the back of the head which you could use to open the mount and extend the jaws. It also had spring-tension in the arms which allowed it to grip things, and the tail was not of rigid plastic but of a more flexible material, so it would bend a little bit.
I understand, though I've never seen it in person, that someone bought the tools for this "action figure" and repopped it in styrene and sold it as a kit.
Here's the best "demo" of the 18" (as an "action figure") I've seen... I certainly don't recall seeing this commercial at the time, but this is definitely the figure!
They are hard to find... and the recent NECA model/figure is definitely a better figure, albeit almost as expensive and almost as hard to find! But this Ebay listing has some great photos, including the original packaging, and reflects the current "market price" for this figure... minimum of $300, and in "mint" shape often as high as $600.
