Produced beginning in 1935, the Hoover 475 was one of the first Henry Dreyfuss-designed Hoovers (famous industrial designers). It was also one of the LAST "coffee-can" Hoovers (as collectors refer to them). That nickname describes the motor head shape of being coffee-can-like. When Mr. Dreyfuss designed the Hoover Model 150 the following year, Hoovers changed shaped entirely, now sporting streamlined motor hoods, and acquiring new, modern features not seen on previous models, including this 475.

Here's a picture of mine. [Some of us have noticed that our 475's seem to suffer from a "lazy" front rubber bumper, which sags]

The Jubilee reference is, I think, denoting the British monarchy Jubilee. However, I have never heard of a Jubilee demonstration bag. Yes, these vacuums were demonstrated in homes by salesmen, though it would not be long (post WWII) that home demonstrations would fall out of favor, and Hoover would step up their distribution and dealer network, essentially cutting out the door-to-door practice for the company.

The tool kit you refer to fitted both the Model 450 and 475 (and perhaps others, which I am not sure about). Perhaps other Hoover collectors with this knowledge could chime in at this point. As to value, like other collectible fields, it largely depends upon what collectors are willing to pay, what condition the machine and tools are in, and how much of it is original equipment (bag, etc.)

Anyone else?
