Thank you for the comments, Bertl, Rick, Nigel, and Ben. It's been almost six weeks since I posted an update; in the interim I completed the "generic" Eindecker sets and received the finished sheets from the UK:

In any graphics project there's always something of a sense of anticlimax when you see the finished product, since you've been looking at the art in minute detail for months. I've been doing graphics professionally for fifty years, but in all that time I never had to work at tolerances of 0.25mm—that's 1/128", if my math is correct?—which necessitated countless corrections and revisions. Some, but by no means all, of my proofs can be seen below (on regular printer paper, NOT decal material, I should add):

In any event, in between that and madly trying to prepare for a show of my landscape paintings—my "day job"—I've been able to get some work done on the E.I model, which is finally up on its (as yet unglued) undercarriage, loose rigging and all:

My attempts at reproducing the sworling on the metal panels are slowly getting better, although I'm still dialing the technique in:

But since I'll be building at least two more E-series kits this year (Projekt Eindecker "warehouse" below) I've decided it's good enough to go with for this initial build.

Per ardua ad astra,
