From Lionel this is the 6-31923 Pennsylvania Railroad set made and sold by "Do-it Best" corporation years ago. It is complete, in excellent condition, never out of the box or on the rails. The locomotive is a "smoker" and the set comes with smoke fluid and track connection. Also included is 8 straight and 8 curve O-27 track and a transformer still in the sealed box along with all the paperwork. Feel free to ask questions prior to purchase.
