These all look like some pretty cool kits.
When I was a kid in the early 70's my grandmother bought my brother and I each a kit that I think was supposed to be a Saturn V. (Not 100% sure, but I remember thinking of it as a "moon rocket.") It really was not a very accurate scale model. It seem like it did not have any tube diameter transitions --- just a very fat tube all the way up to a molded plastic capsule nosecone with a tower and escape rocket on top of that. It seems like there were lots of stickers and stick-on wraps to complete the details. Many molded plastic parts.
This was by far the biggest model rocket I had ever seen up to that point. It flew on a cluster of 3 x 18mm engines --- the first cluster I ever saw, and my dad had to modify the launch controller to add more alligator clips. This also turned out to be one of our favorite rockets to fly due to spectacular crashes. The very first flight was flawless, with all 3 engines lighting (lots of noise and smoke), the rocket flying perfectly straight, ejection at apogee, with the rocket body and the capsule coming down on separate chutes, as designed. Perfect! I don't know if we ever saw another perfect flight after that. Typically only 2 engines would light, and the rocket would arc over and crash down range. We flew them for a long time with the escape towers removed after they had been smashed so many times. Occasionally only 1 engine would light and the rocket would corkscrew up to about 10 feet, flop over on the ground and smoke until ejection. I think one of them eventually did the flop and smoke routine and then caught fire, and the other just crashed so many times it was smashed beyond repair.
I have no idea who manufactured that model or even for certain it was a Saturn V, but I certainly enjoyed flying it as a kid!
