Hello, I need some help on this WW1 German Artillery/Verkehrstruppen/Pioneer kratzchen. I was told that the interior part was original, but the person who gave me it was dubious about the feldgrau exterior part, and of the insignia on it. I was told it was probably restored or asembled. I also want to know who made interiors marked with a Reichsadler,s ince I’ve never seen them, although the interior is of common style.

Here are the pics I took today:

Those are all the pictures.
