Column lock is prewar Ford as far as can be told. Usually the horn button and wheel best way to pin it down, 36 and before are the cruder type. In 37 the pitman went to roller, steer is easier than the gear type pitman. Look at mac VanPelt's site for drawings and probably part number to identify. Wheel should have Ford logo and/or KH stamped into the flats between the lug holes. Yes wheels could be '40 or later, usually the Mercury, lincolin and pickup were wider for bigger tires. I have had 4", 4 1/2", 5" width
