Thanks for posting that Jay, it's very close to what I want to do with my Maxwell. Any information as to when this was taken?
I'm pretty sure these are British soldiers.
They are British, the photo could have been taken anytime after the black radiators came out, these men are not in an active area, as they do not have the correct equipment to be near the front. It is not very likely this photo was taken much after the end of the war in 1919.
