This model was shown with some regualrity about 60 years ago, an early representation of the hoped-for “Nova” rocket which was planned to put astronauts on the moon. I would’ve expect that the model had been long ago lost, but it seems to be held by the Smithsonian… and it’s much larger than expected at 1/72 scale and 48 inches long:
Model, Rocket, Nova, 1:72
You can zoom in on the image at the Smithsonian link above, though good luck on downloading the full-rez version.
I have previously linked to a vintage photo of the model HERE. And if you want one of your very own, Fantastic Plastic is in the process of working on a set of Nova/Post-Saturn rocket models:
