1950's maybe - Jack Arnold - Adoptive Father of my dad: truck license plate: California: 7P 13 26. The jeep or truck or car vehicle looks like a Ford. They were living around Goldhill and/or Medford, Oregon, in the 1950's and 1960's. My dad, Donald, was born in 1950 in California. My dad was adopted most likely before his father, Peter Rasp, died in 1953. So, my dad grew up in Oregon. It appears that my dad's adoptive father, Jack Arnold, had this California license plate car, assuming that was his car. Well, Medford is close to the northern California border.
