That is a Hayes AX600C. Hayes was made in Wichita, KS. You are correct, that face is not for a Hayes....it is for a Wayne pump. Since it has the wrong face, it could potentially have the wrong "clock" mechanism behind it, or no mechanism at all. I did notice it is missing the visigauge too, which would be a small glass cylinder held with a cast iron top and bottom piece. It should attach to the pipe sticking out of the left side of your pump in this photo. To check on the mechanism, you would have to slide the pump out of its hole there and unlatch the door to open it up.
