Thanks guys! That was quick. Is the set particularly noteworthy in any way or valuable? I know that's getting later into the Postwar period and things were starting to go downhill a little bit in terms of quality
Yes, it is very valuable and desirable. The 616 was only included in 2 cataloged sets, in 1961 and 1962. If you have any of the boxes or the set box, you should save whatever you can. The 6500 w/ plane was only a part of this set. Same with the caboose.

Also, I just googled the set number and got an LCCA publication where the author mentions the set and says he's never seen one with a red/white missile with a red tip, but this one does in fact have a red tip. I'm certain it's original, given how long the set has been sitting, and the fact he had no other accessories and bought nothing else for the train (they even made their own Super O power busses from thin sheet metal rather than replace the factory ones as they were lost)
