Morgan, Charles, & Tom,
Best I can give is a ballpark figure on the date of the 903. As I said before in another post, the older 903's had a white (or off-white) bag with red printing like mine, and the later ones had a red bag with silver printing, like yours. They went to the red bag in the early 70's and pretty much stayed with that until they quit making Hygienes around 1980-1982. So, yours was probably built between 1970 and 1982. Mine, with the white bag, was pre-1970. But when I sold them in 1974 and again in 1976, they looked exactly like yours.
And Charles, they DID make a floor polisher for the tank and cannister models, and I have actually seen one. For some unknown reason, our Electro-Hygiene branch never pushed them, or the extra accessories for the upright either, so I never demoed one, but we always kept a few on hand at the store, just in case someone ACTUALLY READ their instruction book and asked for one. The polisher, just like you thought, was similar to the Lux, but actually almost IDENTICAL to the Filter Queen polisher, even had the little wooden handle that screwed into the side so you could use it two handed to polish cars or furniture as well as floors.
And Tom, if Morgan's Hygiene looks familiar, it's the same model (903) as the one I picked up when you, Joe, and me were thrifting last year, which I now have almost finished except for polishing. Also, I think the reason you see more Royals than Hygienes is that EH was mostly sold in homes, where Royals were sold in stores.
Hope this has been helpful.
Jeff
