They look like ex-military ones. It's a tough transmission - the drag-racing trucks use them, and they normally last a very long time before needing work. If they do need work, they cost a lot less than a B500 to overhaul: those ones can cost well into five figures to repair! However, if you're thinking of putting one in your bus, they probably won't fit: they're longer than a MT-6xx, and they weigh more than 900 pounds. The D version has a deep first gear, lower than the normal first.
