Absolutely Brilliant Tiger, I love it. Very much a clean looking example of my favorite Early version Tiger fresh off the assembly line. My first tank in the Hobby was very simular,and fun to construct although fewer resources.
The Air cleaners always were a problem for my as the early Asiatam Hulls opened with the back plate secured to the lower hull. Which I am sure is a problem you have as well,the tube either have to be removed or cut to fit flush at the elbows.
I did add the wiring for the smoke grenade launchers useing a black was coated string, which you might consider? Not at all being critical mate ,I really like your Tiger. Just clean and mean , Imagene being the proud crew unloading a new Tiger at the Height of the Tigers advantage on the battlefield. Wow. I modeled the Grossdeutschland S13 which I was able to find the History of its first months of service and some photos. Just possible you could find a similar Tiger record? Really would like to set both our Tiger together as mine is Grey. Would make a fine pair.
As for the History question, well maybe this will help
