“I have recently aquired some pieces of a Marklin set with rails and all. It seems to be quite an old set with many locomotives and wagons. Where can I determine how old this set is and get some more technical info on it as I do not have a power supply for it. It is a beautiful set, specially some of the loco s. It has a central track power take off system.”
