Those pictures are a Tomahawk, but not the IQSY Tomahawk. Different fin can attachment. By the way, G. Harry Stine would put a slight error in his scale drawings so that he could catch people claiming them as their own.
The NAR Technical Services drawings were done by Jim Coffey. I had half-scale blueprints of the IQSY Tomahawk. I loaned them out and the second time they never came back. I did make a couple of photocopies of the important parts.
I have a page out of an Aviation Week issue decades ago that was a Thiokol advertisement. There is a small picture of a black Tomahawk with what appear to be white fin shrouds. It looks like by the fins in white it says "Astro-Met" and near the nose it looks like "IQSY Tomahawk-1". Sort of hard to read due to the small image. If I recall correctly, the first flight failed due to the fins burning off.
