Small Scale Military Headquarters

Hi
With regard to the king tiger porsche from FOV in 1/72 scale 85401 Holland 1944 i just bought i noticed that it has a sectional gun barrel [2 pieces] which could be correct and at the same time it also has the binocular periscope tzf9b in the mantlet is the combination of this two features correct for this king tiger?
Is there any evidence that the sectional gun barrel and the binocular periscope combination is correct for a porsche version king tiger?
thanks very much for your reply

I've never seen a picture of one, but saying that both modifications occurred at around the same time in May of 1944, I suppose it is possible. I tend to lean pretty heavily on photographic evidence though so I wouldn't model such a subject myself.
