Thank you Herman and Eric,
Spring is coming this week with warm weather, Hagenau is going to melt soon.
The following set of posts are for the rear spade.
Although the prototype had an hydraulic system to lower and raise the spade, it was considered too complex. The production vehicles were given a simple winch, many pulleys and a metal cable.

View from the M12 at Aberdeen before its restauration. The structure of the spade is not obvious and all available references are required to get a full picture of it from all angles.

The middle section has an embedded storage bin and the lid can be raised with the handle to open it. Notice the single diamond thread plate pattern.

Rare view under the spade. As it can be raised, the bottom of the spade is highly visible and need to be detailed correctly. We can see the lower middle section containing the bin and its guard rails.

Both Vandra and Academy did not study the rear spade properly, both are inaccurate.
The Vandra spade is a bit too narrow and too short. the plate sections in the middle are therefore cramped. Use of double diamond thread plate is wrong. The whole bin section under is missing. The blade itself at the rear is not too bad but has some shape and dimension issues. However, i have no intention of re-creating this whole part so i decided reuse the blade.
The Academy spade seems to have correct dimensions but the attachments to the hull are wrong. The larger bin section under the spade is totally wrong, simplified and most details are inaccurate or missing.

The middle section and mounts are too narrow, they do not fit my model. The whole mounting and middle section has to be redone.

Cutting the mounts in order to reuse the blade.

I tried to see if i could salvage the mounts and extend them, but i quickly determined it was easier to create new ones.

New longer and higher mounts are created.
