Yes, I refer to the colour as ivory, which is not as yellow as cream.
Interesting that Hoover changed and simplified the bag pattern. Only reason I can come up with is that it saved a few inches of material so they could fit more bags on a given length of cloth? Also sewing up two less darts would have saved milliseconds of factory time.
T'was ever thus since the Science of Time Management reared its ugly head.
cribbed from Jack C's site:
"The sateen bag (1920-25) was chemically-treated with a dust-proof film. Hoover recommended that the bag never be washed, brushed, or even turned inside-out, because this caused damage to the chemical coating. The thin sateen material tended to wear out relatively quickly, and Hoover's Research and Development department was continually engaged in developing bag materials which provided better filtration, and were more durable.
Model 541 (1923) replaced Model 105, and featured a number of improvements over the former model, more durable bag: double-lined at the bottom for greater durability.
Model 543 (1926-29) was essentially Model 541, but fitted with Hoover's new Agitator. It also featured a bag made of the new, more durable 'Ronac' material, supported at the top by the patented bag spreader device."
"Where will you find a new rubber furniture guard similar to the original? "
Fortunately (?), it's Fred's Hoover, not mine. But I have had to replace bumper strips on all manner of machines.
Key word is 'similar'. On a good day you might have a junker that can donate but visit any Auto Parts store like Pep Boys, Walmart, etc.
Perusing the OEM aisles and the FanBoy Custom sections reveals an astounding array of vinyl trim strips that can serve the purpose. The Home Insulation department is a good bet, too. for rubber trims that can be pressed into service.
I WILL get around to making up some bags; I have a 425 and a 541 from Jeff Schroff Sr - hygiene903 - that came with modern replacements - that will benefit from something more 'vintage'.
Say, here's the 425 & 541 now with handles, tossed on the kitchen floor upon my Grand Tour return. Oh look, a yellow-gold hose that will go great on my Haley's Comet - I knew there was a reason I snatched this orphan hose from Chris'...
Btw, you do know about Jack Copp's invaluable HOOVER reference site:
