Hey Claymore I'd like your opinion on this alt-tank design, it's for a TL where a man from the present (College student) day is ISOTed into the body of a German WWI veteran in 1924.
He invents the ball point pen and makes a small fortune for himself and then goes on to invent more stuff and builds himself up as a businessman with the golden touch.
He has no love for war but wants to make sure Germany can defend itself come the 1940s, he's removed Hitler from the scene and Germany stays a democratic nation. He has a book with some useful information about science, technology and history but the book doesn't have a "How to build the perfect tank" manual.
He knows his history fairly well though and is a bit of a military fanboy ( much like myself), he's helping technology in Germany move along a little quicker than OTL but not too much.
So taking all this into account I've designed a tank that I think might be doable in this alternate Germany circa 1935-38. The tank would most likely start off with a less powerful engine at first and the first main gun mounted would be either the Pak-40 or Kw.K. 36 L/56 or maybe even the K.w.K 42 L/70.
So I'd like to know if you think the design is plausible for the timeline described and if not what changes you would make.
There is no hurry on this, the timeline is currently in the year 1929 and Germany hasn't shaken off the restrictions of the T.o.V yet but they are on better terms with the British but not so good with the French.
