This is a MODERN LIONEL run of a Hudson wheel. As you can see, it is a shade of gray and has a whitewall around the outside. It has the flange, and is one of the outside motor wheels.
It is wheel made for the 8606 Boston and Albany Hudson. Lionel does not make this part any longer. Tough to find.
We obtained it in a small collection from a closed down Lionel service station many years ago. It is a hard to find part.
It has the protrusion for the linkage/siderods, etc. The axle whole is approximately 1/4". There is no tire. The whole wheel measures approximately 1 5/8" across.
CONDITION: New old stock from a service station, and were newly purchased by the service station in the 1980's I believe. Does not appear to have been used.
