This is an extremely hard to find aftermarket aluminum governor for a Fordson tractor.  I don't know who built it so please educate me if you do.  It is part number B101 and is in good used condition with no cracks, breaks, or repairs that I can see or know of.  It turns as it should with minimal bearing wear.  It has the original drive gear fastened to one of the studs as can be seen.  This would be great addition to your Fordson tractor or Fordson aftermarket parts collection or display.  Loose Fordson parts don't come along very often so don't miss your chance on this if you need it.  It will likely be a long time before another one turns up an it probably won't be this nice or include the drive gear!  The pictures tell the story.  You won't be disappointed in any way!  I can be reached at 262 573 193 1 if you'd like to talk about it.  Good Luck.
