Considering my skill level and limitations, I don't feel worthy enough to even look at photos of that kind of dedication to building scale models in brass (or any kind of material). If that craftsman and I were in the medical profession, he would be a brain surgeon and I would be the guy who carried the bandage box.
All of the photos of every part are remarkable, but the lock that can be opened and closed (last 9 photos on page 14), and the operating windows on the truck door (last 7 photos on page 15) are incredible to me.
