Alex does very nice work! I consider the Porsche turret King Tiger the most accurate of the two TCS King Tigers. The Production version turret rear width is too small for some reason. The King Tiger turrets were both designed by Krupp. The Porsche turret was the original Krupp design and the production turret was a simplified design, also by Krupp. Porsche and Henschel designed the hulls and running gear of two different versions for perfomance trials; both used the original Krupp turret. Porsche thought he would win the contract and ordered 50 of the original Krupp turrets in anticipation of the production contract. The original Krupp turret was very elegant; but difficult to manufacture, thus only 50 were produced.
