Ok all. Not sure about this unit as we only use Warner brakes. It appears to me to be a shaft mounted brake of some sort and I'm hoping that someone out there recognizes it and has a use for it. It appears to me to have never been ran. There is a stamp on the unit that says Rockford Dynator and casted in the unit is Dynamatic 305450. Other then that I do not know much about it other then similar units by Warner are very expensive.
