Smow69, please tell about sending the Rainbow in for servicing,, You sent it into the factory im assuming or no? Or where did you send it?
What is the cost involved in doing that? DO they have a rebulding program like Kirby or no? Do they do all models or just specific ones? Do you have to show proof of ownership? How much did it all cost and what all did they do? Plese give all the info about sending one in, thanks!

BikerRay,
Those are the nicest examples A,B,C I have ever seen. Beautiful examples of some really unique machines. Way ahead of their time in the machine and tool design compared to the old dust blowers of the same era. Thanks for sharing the pictures.
 
The Rainbow SE is actually pretty easy to service. The motor is a much simpler design and easy to take apart. Parts are readily available. You can even wash all the plastic parts in the dishwasher.
 
I love the Series A and Model B Rexair cleaners the best. My Series A has a serial number of 8996. It was built the second month of production (November, 1936) and did not use water when it was first sold. No Rexair used water until March, 1937. My black Model B is unique, in that it came with the 4 quart pan with built in wheels. The machine was never used. Got it brand new in the box from the estate of a deceased dentist in Illinois. His family brought it to the Museum.

Something I've always wondered about, I think that the B with the serial number on the top and front is older than the B with just the serial number on the front.

Possibly early 1940's and late 1940's?

Because the B with the serial number on just the front, the plates match the plates on the later model C.

Is this a valid assumption?
 
Only one nameplate on the Series A. All model B cleaners (actually called the Black Diamond model - launch in April, 1940) had two plates (one on top and one on front). There were no model B's with just one serial number plate. You are right, the Model B cleaners with two serial numbers printed on it were earlier. Pre-war model B's had 2 screws to lock down the upper latches - under the dome was a filter called a "muffler". After the war, the muffler was an option. It was changed to a paper filter that you disposed of every three months in 1947 and was completely eliminated by 1950's launch of the model C.
 
The other thing I noticed is that the B with the serial # on the top and front has the A style footed plate, where the hose attaches it has a cutout where as the later B with the serial # just on the front doesn't have the cutout.

First pic is of the early B
