The one that gets me are the listings where they sell the locomotive separately from the "coal-car" (Tender).
Amen Brother. Paradox ! Once you have one without the other you have to find that guy who has the OTHER. I have bought collections where this was the case. However, I can say I never sell one till I have the other. I cannot tell you how many times a month I explain to someone on ebay that you cannot separate the loco from the tender because they have mated electronics. Sometimes they relist with both in one ad but usually not. j
