From Olsen's CD. Didn't show individual Baldwin wheels. FYI -1947 version used same wheels for pilot and trailing trucks, and CD did have wheel PNs for the 1947 version that I have included FYI, PNs being for Wheel + tire. I don't know enough to say the 46 and 47 versions used the same driver wheels.
Pilot ==> Wheels 671-127 , complete pilot 226E-88
Trailing Truck ==> Wheels 671-127, complete trailing truck 726-43
Baldwin ==> three types. Again PNs for Wheels + bearings + axle
