AF back-to-back wheel spacing will vary depending on the vintage of the wheels. Generally, earlier wheels seem to have thinner flanges than later wheels, allowing more inside clearance (assuming the actual gauge is correct.) If you compare closely the wheels of Gilbert rolling stock made over 20 years, you'll notice several design changes in the wheel molds. Also, as the molds began to wear out, wheel trueness got kind of inconsistent, making accurate measurements a problem. I tend to prefer adjusting the wheel gauge by setting the outside of the flange to leave just a slight amount of play between the flanges and the rails when the wheelset is riding precisely gauged track. The amount of play I end up with tends to be less than the factory allowed. I let the back-to-back clearance fall where it will. Chuck F.
