As a result of further research and the gracious help of fellow formites...I've decided to start over!!
Well, sort of
Instead of tweaking my first attempt to fit the new references recently acquired, it'd be just as easy redo some bits.
I did notice the different gun mounts and I think you're right, they are for the Scwarzlose. Even if it was limited to a few A/C, it'd be fun to model the gun. It's not one you see to often.
The E.III replica in San Diego has a 08 with a later (o8/15) cooling jacket too.
Lol..I better get back to it!
more to come....
