I had a J200 for about a year back in the early 70's. I must have thought it would magically transform me into Rev. Gary Davis. I was wrong. It was a sunburst with a pretty scratched up top and the original adjustable bridge (which I changed to a bone saddle) and had Steve Young 1963 written by pen on the inside back. Judging from the bridge I think it was made in the early '60's. I bought it from a sleazy lawyer who lived in Takoma Park, MD. and sold it to a very nice collector from Alexandria, VA.
Not much chance it was yours but I thought I'd put it out there.
