Yes, they sure look nice. May I suggest that the edit your thread title, as these items are NOT "Wheel covers", but covers for the roller bearing side rod crank pins. The axle ends on modern steam locomotive are hollow (you can actually see through the entire length of the driver axles), so putting any sort of "cover" over the axle ends of the drive wheels, might be a bit difficult.
As additional information, everyone might check out the roller bearing rods and crank pin "covers" on the MTH New York Central L4b Mohawk models equipped with roller bearing side rods. They are the absolute best!!!!
