I don't believe that was one of their controllers, but one built by Cutler Hammer for Westinghouse. It looks very similar to a CJ Anderson controller, but your looks pretty basterdized, might be better off tracing wires back. They didn't have many wires to the hoistway do should be easy. I hate it when mechanics change Crap but don't mark the relays or make a print. I've attached a sample of what I've found in the past with Cuttler Hamer controller as far as shaft wiring.
