I purchased a large number of vehicles from the estate of an elderly model railroader.  I do not know their age.  He did not display them on his layout, but rather kept them organized in trays.  Each one has been closely inspected.  Please click the link below to go to the Model Railroading category in my store to see lots more...with more to be listed in the future:
