Thanks Santynus.
IMG how did I not see that?? Just goes to show, no matter how long and hard you look, you still miss stuff!! Grrrrr. Thankfully, easy enough to fix, but still, not the point.
Now that first pic you posted is very interesting . . .I have no idea what publication you found it in, but I have it in "Von Richthofens Flying Circus".
Here it is with the text, and it lists it as aircraft 525/17. (well you can read the text for yourself).
I think the wing tips need a rework too on my templates.
What do you make of that?
