It is Captain K.G. Pulliam Jr. standing beside his decorated Nieuport 27 E.1 that is at Issoudun, France, May 21, 1918. Called the Jazbo.
Stationed at Field # Four at Issoudon 3rd AIC and called the "Jazbo". It is one of two similarly marked machines at Issoudon France 3rd Aviation Instructional Center. Probably at Field Four. It was called as the hand written caption names it "Jazbo" the other machine was called the "The Flying Fish." The Current Cross & Cockade International Vol. 37 #2 has two articles about the units at Issoudon (written by some plugger here abouts.) The Jazbo is shown there in a colour profile. "The Flying Fish" , was probably green, white,red,silver dope and black to various degrees.
http://www.crossandcockade.com/There was another there that had scales painted in an elongated 6 sided hexegon down the fuselage called the "Flying Fish" it had a similar scheme with teeth. I am hoping to get a decal maker to do this as a set.
