I stand corrected on the cross brace,it must have been added after production.I have a great book on the DR1,and they never mention the crossbrace.The book has blown up plans and goes in great detail on the construction,nothing on the cross brace.There are dozens of WW1 pics..and if I look real close a couple do have the cross brace.My guess is if a DR1 survived for any length of time the sub-wing started to come loose-jeffo
Scale modeling teaches you to search as many sources as you can find. I cannot tell you how many books I have on the tripe. Many detail items come from several different sources. Some details are also proven to not be accurate as well.
A great example is the wings pallete website. Good for ideas, but cannot be taken too seriously.
