Thanks for the link to the serial numbers list. I have a couple of questions about that.
First off, I wonder what the models 1 (1937-39), 12 (1953-56) and 14 (1955-57) were. This is indicated as a list of upright models. I don't recall ever seeing any of these Hoover models before.
Then, I wonder why the Model O and other early "pre-numbered" models, and the 102 were overlooked.
Next, I see the compiler of the list had overlooked the 62 which someone added by hand.
Finally, I'm sure the 105 did come out in 1919 and not 1920 as the Hoover list indicates. That information came from Stan Kann "way back when," and he was very meticulous about Hoover dates. This would not be the first time there were mistakes in archival materials produced by a vacuum cleaner manufacturer.
It's interesting to note that the 27 came in both steel and aluminum casings. I wonder if there are any outward differences (trim, etc.) between the two that would distinguish them.
Oh, also, I see there are two different serial numbers for the 105 -- 575,000 to 674,900 and 5,000,000 to 5,299,999. However, the five-digit serial number on mine is very clear.

In other news, I got the following very interesting and informative information from Tom Gasko:

Beautiful rebuilt Hoover. You did an amazing job on it.
Here's a few things you might not have realized, but you'll understand they make perfect sense in retrospect:
That Hoover was rebuilt by a vacuum shop or any number of concerns rebuilding vacs for sale to vac shops (like Buckeye or the Henry Company).
It was not rebuilt by Hoover. Why did I know this? Had Hoover rebuilt the machine, they would have used a different nameplate with the words "Previous Model Reconstructed at the Hoover Factory". All Factory Rebuilt Hoover's had this wording on the new nameplate. Your machine has the original serial number plate, held on by screws rather than rivets, as Hoover used originally and would have done on their factory rebuilts.
You have a Robbins and Meyers motor, which Hoover discontinued using with the model 102. ALL model 105's had Hoover-Built motors. Your switch is on the incorrect side for a 105.
Your bag spreader didn't appear until the model 541.
By the way, the belt is for a Premier/GE/Universal/Eureka type motor driven brush machine.
While it's beautful, and you did a wonderful job, I just wanted to point out that it was not, in fact, a real Hoover factory rebuilt cleaner. Nonetheless, it's very collectible and gorgeous now that it's done.
Let me know what the next one you get is? Hopefully a 150. Or maybe a Norca model 1 or 80 - now wouldn't that be something?

I gave him a call to thank him for the information and he told me some more interesting things on the phone.
He said that the designation "Special" meant it was a household model.
He cleared up the mystery about my five-digit serial number. He said it means that mine is a very early 105 - noting that the last patent date on it is 1920, while the later 105 has a last patent date of 1922 and has a seven-digit serial number.
-ooOoo-
This 105 surely has turned into a wonderful and interesting excursion for me!
