And to answer your next question:
This is a 502. On the bottom it's marked (12 502 64) so I'm assuming it's a 1964 model. I believe that's when it was bought. We took a trip West to Boise to visit relatives and I believe my Dad bought it for me on that trip. I so It'd be 45 years old. Still had the old gas in it (I know, I know a No No) and no the gas wasn't 45 years old!
Found this also, which I thought I'd lost, in the same box
