Recently I bought a used Polar Express set [6-31960] and the locomotive was missing a small cover that is between the boiler and the bell [see photos below, first one is my train. second one, shows a stock photo with the missing piece]. I've contacted Lionel and several other online trail dealers and they have all said that the part I need is not available and that I'd have to buy the entire shell. I was wondering if any of you folks knew where I could get just the missing cap. They also said, that any shell from a Berkshire should work.
Any help would be appreciated!
