Ok, I know this info is out there but I can't find it...this is a 12 inch ( I own 11 tape measures but can't find a single one so am guessing ) 75423 AB1, AOU brass bell, brass blade steel cage 1922-ish w/ no pot metal so far....it seems to have a 4 conductor headwire that's been butchered into a 2 wire but I can't get the stator out. Using a punch through the air inlets of front cover while dodging the windings is getting me nowhere and the crappy thing is that I've done this before a few years back on a early 3 star GE but am having amnesia. I know it's doable, but I am not even sure how to rewire the head once and if I even get the bugger out. Tony Clayton can get me the wire but he probably thinks I'm blowing him off because I can't be sure if I need 2 or 4 wires from the head. It seems to have a speed controller but want to bench test before ordering from Tony, and I don't know squat about GE speed controllers anyway so please, any thoughts would be very welcome. BTW, a big THANK YOU to David Houtson  for pointing out the setscrew that holds the big brass screw into the gearbox....that was driving me crazy for days...thanks for pointing that out! Also, the base tag on this fan is totally beat to death, anybody making these anymore. Thanks, John

On the 4 wire GE headwires, there is no speed coil. Instead there are multiple windings in the stator, and the switch simply energizes the different coils to change speeds.  It’s possible that one of the coils in the stator went bad and the owner just cut off the wires going to it to make a single speed fan. The only way to tell would be to pull the stator and see how many wires enter into the coil.  Apparently there have been instances where GE used 4c headwire in place of 2 wire but I’ve never had one.  
Those stators usually come out quite easily with the pipe method.  Maybe dribble some penetrating oil between the housing (not a lot)  and stator core and then use a heat gun to heat the housing before trying to remove again. 

Hope that helps.
