The center pic shows the cut to be in the window area if it was a tudor so unless somebody put in a piece of wood or sheet metal, that looks like a cut down sedan delivery.
That is what I was thinking as well. If it was a car cab there should be a window.
I got dimensions of the door.
Top to bottom 42 3/4
Front to back at handle hight 27 5/8
Does that narrow it down?
