Looking closely on the side of my Lackawanna's cylinder and you will see a "J" class plate. I am guessing that they all are like that.
At the time these came out, before the scale revolution, I thought that they were the best looking of Lionel's steam locos. I changed out the bearings (because of the OGR article) before ever running my loco. Mine runs great and has steam chest smoke.
