Well, now I have begun building the kit in earnest. Please keep in mind, this will take a long time, and updates will be infrequent.
In the following posts, I will show, what I have done so far.
The starting point is the frame, which is so to speak, the backbone of the vehicle. I work from the Technical Manual, unlike Trumpeter and Italeri
(How I do not like this texteditor, Armorama, get it fixed, for crying out loud....)
The grey bar to the far right is Trumpy part C22. It can be used as is.
The part to the left of Trumpy C22 is Italeri part #3, dressed up with braces and boltheads. This part matches parts #15 and #17 in the picture from the TM. Please note, part #17 in the TM is not quite right in the TM drawing. In real life, there is a vertical plate "hanging down" vertically from #17, which can not be seen in the TM. This vertical plate is part of Italeri part 3. See the yellow arrow in the picture below.
