Can anyone find a manual or which cams go to this please. I have found no information on this model. There is tons of information on the 803A but nothing on this model of the 803 except I know it was made by Riccar. The casting of the machine has Riccar stamped on it. I would appreciate if you could find a clone like it somewhere. Must be one out there someplace. It is a Free-Westinghouse. Glowygirl2
