PHANTOM III. GEAR BOX GEARS PRODUCED IN U.S.A.

This box has been recently tested in 37-EX. Chassis, and is now in the Experimental Department for further instructions.

We suggest the box be stripped with the object of investigating the wearing properties of S.A.E. 4620 material under load conditions.
