assuming that there is some reason behind the 'primer' scheme given in the Trumpeter kit, i guessed that this denoted that the mismatching barrel and manltet were taken resectively from older/scrapped vehicles and fitted to the prototype? i think i read somewhere that the idlers/drive sprockets came from the RSO (given that the RSO was produced by Steyr and perhaps at the same factory then these parts could have come straight off the RSO production line and could be in primer when fitted or fitted to the Waffentrager before it was primed as a whole minus mantlet and barrel).
so, my question is: if this was the case (i.e. there is some truth to the scheme), where did that mantlet come from? it does not ring any bells thinking of existing vehicles, especially those of the 'panzergrau' era...
of course, this scheme could likely just be total fantasy on the part of Trumpeter or New Connection before them.
...and thanks for the clarfication about panzergrau - i probably had that in my head from something (evidently inaccurate) i read many years ago
