BTW, I don't think I'd call the Proctor EIII fittings scale but rather "scale like." Even the fancy "Fokker style" bolts they sell aren't actually shaped like the originals. For that matter the shape of the Proctor turn-buckles are also not like the turnbuckles used on original WWI era aircraft (they're too thick to be truly scale). The point here is that ultimately a completely 100% scale sctructure is probably unobtainable. All we can do it get the effect right. Donnie's models are certainly an inspiration.
