This is P-51D, N5439V, 44-84745. Believe photo taken at Covina, CA, 1963-1965 time frame. Aircraft at that time was owned by Cline Cantarin of Lancaster, CA, or Stanly Korzet of Covina, CA. Aircraft later to N851D#2, and is now with Stallion 51 as Crazy Horse.
I won't enter into the identity of this A/C, but the photo was taken at Brackett field in Pomona, CA. This '51 and the Bearcat in the background were used in the movie "Wings of Fire" starring Suzanne Pleshet (sp?) filmed at Brackett. I think I took the photo in 1971.
