with Norfolk being a navy town, I'm betting that your 'original owner' was a Navy man in '69-70, Len!
I was in the USAF during those years, stationed at Keesler AFB, MS, and our hobby shop was like a 'Muscle Car Gathering' every weekend when it was open during those years. We didn't have or make very much money, but be assured we spent it ALL on muscle cars..
PS. Does your car still have the front guards on it, Len? Mine doesn't have, but I have NOS ones I intended to install, but now I'm having second thoughts. Do you like them?
