Been an AF “S” gauger for a long time now, and recently got interested in their pre-war “O” tin sets. Can someone tell me if the tin metal O wheels are supposed to spin/turn on the axle, or were they originally attached to the axle? Also what should the measurement be between the flanges on those wheels?
Like other tinplate trains, the wheels should spin freely on their axles. The axles have rounded edges stamped in that keep the wheel spacing at the proper width, so there’s no real measurement for the flange distance.
Thanks got the info. Now I see the crimps that keep the wheels in gauge. On further inspection, I found that one of the axles is bent. Does anyone know of a parts dealer that carries AF O gauge axles and repro tin wheels?
