Help. please. I have been trying to identify the time and place for an album of old photos that show a group of American workmen who appear to be salvaging old WW 1 aircraft. The pictures show these men in a landscape devoid of trees that is harsh, cold, muddy and flat. There are a few U.S. sailors in the pictures. The photos posted here show some of the planes they are dealing with. Correctly identified, I hope these planes will provide a clue as to where the pictures were taken. Insignia on some of the aircraft appears to be a dark circle surrounded by a light circle. Could this have taken place in Siberia? Alaska? France? Any thoughts you might have would be appreciated.
