Hello, all; Purchased a group of UP passenger cars on the auction site recently and the group included an incomplete UP set: 106-1102. Three of the cars were included, but I know that this set also included a coach, and I can't seem to lay my hands on the car number. If I see one at a show or for auction, I need to know it's the one I am missing! Any of you guys have that set, kindly let me know the coach reporting mark, please? Many thanks, Henry
