Named British Made WWI U.S. Army Air Service Observer Tunic and Overseas Cap With Uncommon Wing

The tunic and overseas cap were worn by Julian Langson Lathrop, a Harvard student who served in the First World War as an ambulance driver with the American Field Service and then as an Observer with the U.S. Army Air Service. The tunic is British made, having a Liverpool tailor label in the collar which bears the handwritten notation of “2nd Lt. Lathrop”. The tunic is a fine quality olive wool, which on the collar has two officer “U.S.” insignia and one artillery officer branch insignia. On the left shoulder is a multi piece wool patch of the Second Army. On the upper left breast is an uncommon fine silver bullion Observer wing with “US” in the center of the “O” , showing typical age toning. The lower left sleeve carries a single overseas service chevron. Accompanying the tunic is a British made U.S. Army officer overseas cap with red piping for the artillery branch and a gold Second Lieutenant rank bar. The tunic is in excellent condition, without holes, stains, or damage and, while it shows signs of actual wear, it makes an excellent appearance. The overseas cap shows somewhat more wear and use, but it is in very good  condition, with some spots and fading of the red piping. The tunic and overseas cap have with them a photocopy of an entry about Lathrop from a 1920’s book about Harvard students in World War I. Also included is a photocopy of a photograph of Lathrop in the uniform of the American Field Service.
