There was a little debate a while ago about the 'correct' steering wheel for the CCKW. Some posted that the 4 spoke metal hub with a wood rim was the only correct wheel for the CCKW, and that 3 spoke bakelite (ir whatever material it is) is not, it would be a wheel from a Canadian CMP or a Chevy.
Well, after seeing quite a few late war trucks with both type, I dug in the manuals.
TM9-1801 page 260 fig 145 show removal of a 4 spoke'r. Less than 10 pages later, page 270, fig 154 show a 3 spoke'r. The TM was dated 03/44.
