It's a little hard to read the number but if it is 1105386 it would be used on an Allis Chalmers HD-9, HD-15 (1951-55) and an HD-19 (1950-53)
I gotta look at it morrow, i didn't see it starting with 11. duh. thank you
Rest of the specs:
"A"circuit generator
clockwise rotation
16-18a output at 2400 rpm
