This motor was probably manufactured in the lat 1970s or early 1980s.
Leland seems to have been based out of Ohio,  I called the last known number
I could find for them and got GE Aviation.

Just for the heck of it I check the impedance between the main 6 leads. I
get about 20 ohms between any two of three wires and 2 ohms between any 2 of
the other three.
