44-84660,a TF-51D that went to the Fuerza Aerea Guatemalteca, with reg. FAG-345, and later returned to the USA with the other airworthy FAG Mustangs. Registered N38228, it crashed near Big Springs, TX, in 1976.
Martin has gotten it right! This is the only TF operated by the Guatemalan Air Force; the photo does not show the color scheme as it should be, since it looks darker than what it was in reality. Another great photo by Dick Phillips! Saludos, Tulio
