Mike,
I know that the 38(t) was used by 7th/8th/12th/19th and 20th Panzer divisions in 1941 and the 38(t) was used by 6th Division.
In mid 1942 8th/19th/20th still had some, 22nd used a lot of them and there were a few in 1st/2nd/27th.
What I can't find out is which version i.e. A-G. A,B, and C are very similar but the D-G are noticably up armoured. And it is which version I am attempting to find out.
