Prufstand XII

[World B4]

I've seen all the surface-level sites claim a prototype was manufactured, and subsequently captured by the Soviets, but no photographs... it would surely have been of interest and worth studying, or mounting as a victory trophy, right?

 

[World B4]

I guess what I’m looking for are German and western primary sources to clarify what intel the English speakers got on the program, and Soviet sources that prove/disprove what we think they learned or obtained.
