This would be N8673E, 44-74430. Photo taken most likely at Bakersfield, CA. and if date is correct probably owned by Gerald Smith. Aircraft later exported and became YS-149P, TG-REI, N2265P, N52HA. It crashed on a ferry flight from Guatemala on 6-6-78 killing Dr. Burns Bryam.
I believe this is N332,45-11471,probably owned by David Maytag at the time of the photo.
See Case#: 52 for details.
this looks like russ schleechs n332 at the 1966 Lancaster

This is 44-74430 N8673E. After going through several owners it was exported to two cousins in Guatemala who operated it for a decade. At a time when their own Air Force used the P-51D as a front line fighter. Later sold back to the US, the 51 crashed on the ferry flight, killing early warbird stalwart Burns Byram.
Dave Maytag's N332 (1964-66 time frame) had a similar paint job but without the pinstripes around the white scallops on the fuselage. The airplane was dark brown and also had a P-51H propeller. N332 went on to Dave Zeuschel and then another owner who crashed the airplane fatally.
