Profannie, I am laughing, because I secretly had a hunch that with your luck, it would be a Centennial! (Because she did not know about machines, yet she said 1950, which gave me the hunch that she had seen the badge.)
Very nice for you.
And you know, the lady would be very happy to know it is going to a loving home. I got a FW Centennial quite cheaply as well, and I tried to tell the seller that she could get much more for it elsewhere, but she was actually just really happy to sell it to me because she liked that I was honest, and she liked the idea of it being used and loved. So, good for you!
