I am delighted to discover the Sd KFz 234/6 and /7, and the AufklärungsPanther, none of which I have previously encountered. Although now I’m worried about what the Sd Kfz 234/5 might turn out to be — 37mm Flakwagen? Flammenwerfer? PAW-800 tank destroyer?
Still, it seems a little harsh to call the RSO mit 7.5cm PaK “too obvious” just because it really existed. Given the obvious age of the starting materials, I’d love to know where you got an RSO in the first place!
All the best,
