I loved American Flyer S gauge trains !!!!
They were so much more realistic than the more popular Lionel O gauge.
I had one where you could put 3 n 1 oil in and it would blow smoke out of the stack.
The train is the "New City of San Francisco" streamliner.
It was in service from June 14 1936 to May 1 1971.
The car is a 1936 Willys 77 sedan.
It cost $500.00 new !
Another thing to consider is 67 904 input shaft and TC are a one (1) year only size.
I found that out the hard way. A TC I bought for what I thought was the right one, would not work. (not Fit). I had to buy a later year 904 !
