I was recently given a "Flap Motor" 40:1 reduction gear assembly. I think I am going to use it with a variable speed motor to raise and lower the knee on my mill. It is 8.5 in length and 5.5 in high. The name plate says "Air Forces (sic) Spec 3587-Y"
It is really not necessary that I know what aircraft it might have been used in, but I thought it would be interesting to know. Anyone recognize it? What can you tell me about it. Any information is appreciated.

Added a few mins later: I think the Y-3587 actually does not specifically refer to this assembly but is rather a gear oil-type specification as I found reference to this type of oil in an old Allison Engine Handbook.
