Since I'm a bit taller (6' 1"), I've always been intrigued by the King Size American. A bike made for me! So over the years, when I've seen them at swap meets, I've bought them. Most have them have just been bare frames or basket cases that I figured i would build up into riders which I've done with a couple. So the other day I thought I would look up the serial numbers on the frames to find out their build dates. Out of 4 frames, this is what I found: C228395 - Mar 15, 1962 - Blue C228599 - Mar 15, 1962 - Black C228831 - Mar 15, 1962 - Black B322774 - Feb 11, 1963 - Black Notice any similarities? I guess it makes sense that since the frame was a low production frame and probably required some retooling to make that they had runs of them on specific days. It just seems like an odd coincidence out of such a low number of frames, that all of the 62's I have were built on the same day. I'm wondering if others that have King Size Americans have similar serial numbers on their frames. Anybody care to share their KSA serials?
