Well.... I can tell you my bus has a B300R (R indicates retarder). Yes it's a 6-speed box, but in my Blue Bird it's configured to exercise only 5. That Thomas probably is also, but Thomas has shown themselves more willing to cooperate with a person who wants to pay Allison to change that.
The auction lists it as a 6.6L engine. It's wrong. The data plate indicates ER6CTA250 -- the non-electronic Cummins 8.3L.
Looks like a nice bus.
