Geoff invited me to his place after Fanfair to see his cacti (we both collect cacti) and his fans. Since my other visit to his fan barn with its approximately 2800 fans in 2001 I have been wanting to take another look. Though it was hot and I was tired from Fanfair and a lot of driving I got my chance. One thing I wanted to check out was a strange Century skeletal fan (stationary) that I had noticed during my 2001 visit that even Geoff didn't know what it was.
That particular fan had been stripped of its oilers, motor tag and switch. Just one look and it was obvious that it was neither the common S-3 nor an S-4. Motor diameter was about halfway in size between the S-3 and S-4. Why couldn't that fan still have had it's motor tag!
Here are two "common" S-3s pictured.
The two vs four bolts through the motor may not be significant as I noticed in Geoff's collection of many skeletal fans that S-3 stationary Model 14s (fan on left) have the four bolts while Model 15s (fan on right) and all oscillators have only two through bolts holding the motor together.Attached Image (viewed 136 times):

| Overhead shot showing relative motor sizes. Mystery fan on the right, S-4 in the middle and S-3 on the left. This S-3 is a Model 15 with the two bolt motor. Note the different arrangement between the Models 14 and 15 in the two photos. Attached Image (viewed 133 times):

Left to right: S-4, mystery fan, S-3 Model 15.
I am wondering if the mystery fan may be a late skeletal fan made right before or during the time that the last 16" S-3 fan with enclosed motor was made since there seem to be no corresponding 12" enclosed motor S-3s.
Sadly, with the missing motor tag, we may never know what that mystery model is.
Note that the mystery fan is a 6 blade one. Could it be that the motor on this fan was larger to run the larger blade? Does anyone know about 6 blade skeletal fans and if they are rare and might always have the larger motor?

| Interesting Steve! I'll measure my S3 six wing & S3 4 wing tonight to see if there is any difference there.

I always thought that more blades = bigger motor, so wouldn't the same be true here? Also, the vent holes on the S4 are arranged the same way that the ones on the mystery fan are. ???

| Like GE, Century probably "morphed" their fan line when production went from the S4 to the S3. I know the early S3 switches will fit the S4's. I have only seen one 6 wing blade on a Century, in Mike Robert's garage, years ago. On closer inspection, that was a GE blade. But I never say never.

Steve, I was hoping you'd chime in here. The mystery Century is a later model with stamped steel base and, maybe, two bolt motor (if that makes it a later model) so the fan wouldn't be a morph from the S-4 to S-3. Did Century make both models, S-3 and S-4, concurrently for a while? Do you have any catalog info for Century skeletal fans?

Steve I have almost zilch on Century fans. Thanks to Paul Pierson we know the earliest history (1902-1904). I have one Century fan catalog, but I think from the 20's or 30's. But we do know when Emeron went from the 1500 to the 11644, they used up parts early in the 11644 line from the last 1500 runs. We're pretty sure GE did the same in the Pancake lines. Or this fan may well have been a S4, sent back to Century when it's base got broken. Another mystery.

Mystery for sure Steve. If that fan had been an S-4 the motor somehow shrunk quite a bit in size during its rebuild. Not knowing about 6 blade skeletals I think it's a good possibility that the larger motor was made for the 6 blade model. All we need now is for someone to have the same motor with its motor tag intact.

| Steve, the mystery remains. I measured my 6 blade Century & it is the same size motor as the 4 blade.
