32-68150-1 comes up on the eckler website as a window regulator repair kit w/6 tooth gear.
With due respect to Terry, IMHO the spring inside the housing in combination with the spider on the gear and the slots on the handle shaft act as a clutch. This keeps the window in position when not winding the crank.
There were at least 4 variations of regulator clutch housings common to the 1928-34 years. I have seen "beehive" housings (like the reproduction) with two different pilot bearing diameters, "tuna can" variations, and variations that use rivets and variations that use tabs to attach the housing. Most likely this is due to Ford sourcing the regulator assembly from various manufacturers who each built them differently. The handle shaft could be steel, or "die cast" (which is often half melted away due to corrosion).

The reproduction is "Industria Argentina" and may be "C*R*A*P*, at least two steps below the worst Vintique part. I have seen some OK ones, and ones where the machining on the shaft is so poor you would not want to use it as a fish line weight. One good touch is the pilot bearing is an insert which can be reversed so it will work on the two most common bearing sizes.
