Tom -- I thought briefly that my set could have been the 5114, as both Doyle and Bubeck books suggest that the color of the passenger cars could have been either red or green.  But, the kicker is that the baggage car in the 5114 set is the #718 operating mail pickup car.  My set came with the #651 baggage car ordinarius...  Set box?  Nope - probably didn't survive the early years of my youth.
