I do have an Eureka Emperor, and they were also badged for Montgomery Ward, and maybe more. They were made by Panasonic, or actually Matsushita I believe. It was Eureka's attempt for an upright with a concealed bag, a la Dial-A-Matic style, and had a handy front tool conversion. From what I understand, I'm lucky to have one that works, as there were motor problems with them. It was their top of the line along with the Empress canister. It has an adjustable heighth handle, two-speed push-button control panel, and a cordwinder. I even have a supply of bags, but afraid to use it too much for fear the motor will fail, so it sits proudly in my collection.
