Oh my, it’s the Amerika-Rakete in the left corner of image no. 6!
To me it looks like what’s usually referred to as Aggregat 9, i.e. the upper stage of the proposed suborbital ICBM intended to target New York. Note the prominent curved, bladelike fins running along the whole length of the rocket, much unlike any other design today. Of course it could be just a concept for a Wasserfall-sized AA-missile, or an idea for an A4/V2 variant. Yet this photograph clearly proves the image of the A9 prevailing today is based on a real wind tunnel model, and not just made up. The boxart example I‘ve inserted is from a Special Hobby kit. While I cannot spot the A10 (the lower booster stage) among the shapes, this picture is the first palpable historic trace of that design I’ve come across so far.
And I’ve really been looking for it! The other day I had an argument with a friend, after we walked to an old V2 launch pad in Westphalia. Today just an overgrown slab of concrete, partly destroyed when a rocket exploded on the site itself. In the vicinity a tree still shows the carvings of a guard stationed where the rockets were fueled on their Meilerwagen trailers. So I argued I could believe the Amerika-Rakete was a real conceptual design, something that actually existed on paper and in the scientists’ minds - be it manned or not. After all, later von Braun did build two-stage rockets once he had the means. My friend challenged me to provide a document, a picture, some sort of proof this is not just a modern myth. A popular scale model means nothing, and who says illustrators don’t just copy from one another? For example the text in my other picture claims to show a wind tunnel model, but it’s clearly just a drawing anyone could have made.
Well, I’m one step further now, thank you very much indeed!
