This is P-51D 44-84952 N210D, most likely while in the ownership of Joe Hartney.
This photo was probably taken during the early 1970's when this aircraft was owned by Joe Hartney who was a local attorney in Chino, CA. He kept it at Aerosport and only flew it on few occasions.
Joe Hartney dated my grandmother for a while before he died. My grandmother flew with joe a couple times in this mustang, and I got to "help" wash it when I was 4 years old. Joe also had a Decathlon that he gave me a ride in. He inspired me to love aviation, and later to fly.
