I have a picture of these seven men, Max Hummel, Wilbert Lack, Lt. Heid, Les Hein, "Wee" Humble, "Red" Dye, and Dewval Wright. It is a group picture of them with a bomb. Does anyone know any of these men or anything about the unit? I also have pictures of my dad, Max Hummel, at Aberdeen Proving Ground in Aberdeen, Maryland from 1943. It was the Ordnance School. From the pictures , Les Hein, was in Maryland as well as Europe with my dad. He's in quite a few of the pictures. Wilbert Lack is in quite a few of the pictures in Europe. Thanks!
