I’m doing well, Keith - thank you for asking!
John - Eureka introduced a hinged canister lid on their Empress One machines - around 1967. Before that time, their “canned ham” MobilAire and Vibra-Beat canisters all had completely removable bag compartment covers that were secured with a top-side dial on the roof of the lid.
The first 1967 Empress came with an elegant white braided hose and a thin suitcase to hold all the tools. It also had a big “Vibra-Clean” rug nozzle.
This second generation Empress Two debuted around 1970 - see the link below for a print ad from an October 1970 edition of Good Housekeeping. I think the pale green Carry All Tool Caddy came with the top of the line Model 1880 you see in the advertisement. This deluxe version had the extra deluxe tools (Vibra-Beat nozzle, Groom-a-Pet Tool, square horse-hair dusting brush, 12 inch floor brush).
If I remember correctly, the model line up from basic to deluxe was 1820, 1840, 1860, 1880. 1880 had seven suction buttons, 1860 had three and the other two had none. I think the basic 1820 had no Cordaway cord reel either.
