It really was a great find, although all is not always what it seems in small internet photos. The set does have several "problems" that would reduce its appeal to many serious collectors. It really isn't as perfect as we would like. We would rate most of the items in the set as C6 (the old system "Very Good").
But, that doesn't really diminish the experience of finding a hard-to-find version of the postwar trains many of us love so much.
Although an item may not be collector grade in the eyes of many, getting the chance to run it still brings me back to some very happy times in my youth when my father was first introducing me to the fun of model trains. Considering how things have turned out for me in this hobby in the 60+ years that followed, I think he was very successful.

Many times, to me, a C-6 is better than a C-10. I relate it to my collector cars. My 73 Javelin is a winning restored car with some rare options. When I drive it, I don't trailer cars, I am always nervous about some idiot running into me. (or a deer)
But when I take out my unrestored Matador I have fun as it's just not as rare or refined.
Same with 50's era Lionel.....You can run your set and have fun.....not worrying that if it derails and takes a bump you loose an investment.
I like it!
