Lynn,

Just jumping in here:

From 1940-1941 Army Parts Catalogue:

*C01Q 17508 Motor-windshield wiper- R.H.
*C01Q 17509 Motor-windshield wiper- L.H.

From my 1943 F15-A Spare Parts List:

*C01Q 17504 windscreen wiper assy. R.H. (incl. spacer and nut)
*C01Q 17505 windscreen wiper assy. L.H. (incl. spacer and nut)

There was also motors listed in the 1943 List with C29Q prefix and "B" suffix. "2" signifying the date of release of the part 1942.

Additionally the earlier released motors, "0"-1940, are listed in the 1943 List.

*C01Q 17508 Motor-windshield wiper- R.H. When stock depleted supply C01Q 17504
*C01Q 17509 Motor-windshield wiper- L.H. When stock depleted supply C01Q 17505

So based on that I would conclude *C01Q 17505 is a later model wiper motor, Cab 13. "Spacer and nut" could be the manual arm bracket as its shaft has the nut on it. The wiper motor has only 4 slots in its drive to engage the shaft in the "spacer".

Where is Superman with x-ray vision when we need him!

Cheers,
