Of all the early war Panzer IVs, I'm really glad Rubicon Models will focus on the D/E. It was the more important one of all the ones from A to E, and more D/E were built than A to C.
A = 35 October 1937 – March 1938
B = 42 April 1938 – September 1938
C = 134 September 1938 – August 1939
Total = 211
D – 229 October 1939 – Mary 1941
E = 223 September 1940 – April 1941
Total = 452,
or more than twice as many as all that came before. Also the D/E saw more action than the A/B/C making it more useful for the normal gamer.
Like many others here on this forum, I too will not lose sleep over the idea of using a D/E for a A/B/C in a game of BGWW2, CoC or BA.
