Stik - thx for that link, never seen it before, but really is interesting to read. Regarding the Bison decal sets, I consider myself lucky now, I had ordered them from a Canadian webstore just as this GB was getting underway. I went to check for you if they still had some available, but they are sold out.
Eric - regarding tracks mounted on Kursk Tigers, there is a very informative thread over at Missing-lynx where member(s) have provided serials of the tanks present at that battle (and to which unit they were assigned). Turret brackets for spare tracks was a modification incorporated with production models numbered 250207-251346. So armed with that knowledge, just cross reference the two.
That is an interesting statement from Jentz regarding two tone Tigers in Africa. I agree that officially, the tropic scheme should be present on all equipment sent to North Africa, whether this was followed to perfection with every vehicle, I am not sure. The Bovington Tiger was from the 504th battalion, arriving only in March 1943. So it is being very confident to state that those that arrived previously (as early as Nov/Dec.) must have been painted the same way. I found this thread raising my eyebrow, and raising some doubts: http://www.network54.com/Forum/47207/thread/1350507698/Beute+KV2+-+is+it+in+grey+or+green-!
As I am writing this, an idea popped up like a light bulb - though it possible it has already been put in words elsewhere - but consider when dunklegelb was intoduced in 1943, the factory did not apply any other camou colors, but instead shipped equipment with additional tins of brown and green so field units could apply as required. Could this arrangement been a result of past experiences where vehicles were destined for one theatre, but then ended elsewhere, either due to error, but more likely a transition of priority due to battle losses incurred. Essentially , I think it is possible some panzer grey Tigers were shipped to Africa, and while in transit, were at that point painted a more suitable color.
regards,
Jack
