Thats just the photo i was looking for Viktor. I had a very dark copy of it and couldn't make out the detail.
Ok the antenna storage tube is there but now the question remains where are the rest of the antenna mountings. We should be able to see the pot on the rear deck and the brackets for the mast on the rear hull side.
It is just possible it wasn't a true Befehlswagen and had just borrowed the antenna tube from something else.
Look how obvious the fittings are on the Kubinka vehicle and compare that to what we see on 008.
