Lets see if I can follow flyernut and get a picture posted. This a rather common engine with an uncommon set of cars. Set K5418T from 1954. The 303 Atlantic with the Chestnut striped cars. I have the wrapper and the car boxes(packed away) but no set box. Picked this up from a friends friend. He was the original owner and his brother had the K5419T freight set with the same 303 Atlantic. I bought that one too but it was played with a lot more than this one.
