Small off white Eureka
Both of the smaller canisters are Eureka Princess models or the equivilant of with another company name. The off white is the model sold by JC Penny. Penncrest was the name JC Penny used at that time. The Viking model and the Penncrest both have the same motor wattage and both clean equally as well.
The Penncrest model has a cord winder and what I would call the basic set of tools including the Vibra Beat. The Viking however has the deluxe set of tools, horse hair square dusting brust, better upholstery tool and the bare floor brush also has the horse hair bristles. The hoses are identical on both.
I have no reason to beleive the cord has been changed on the Viking as I beleive it was never used, but the cord is black as compared to most Eureka's similar using the cream colored cord. Perhaps Clay or someone out there will know that answer to that question.
Both take Style H bags and use the little filter discs. Also, they both have the vent on the bottom of the machine that you can open and close to use the blower port on the back of the machine under the lid latch. So when you use the blower the bag compartment is actually open so that you have the strongest air movement for blowing.
