Paul, I've been somewhat delinquent lately in responding to posts but I'd be remiss if I didn't comment on your J1. I've got one of these in my "someday projects" and I'm planning on finishing it in a similar scheme as you have (solid finish). Hope mine, here in the distant future, turns out half as good as yours.
The weathered finish and field wear and tear all look excellent, really like how you've done a subtle stain on the upper wing from the exhaust. And from the Junkers DI I built years ago (Roden, long fuselage) I know what a nightmare it is to try to put decals down on that corrugated surface... decals look great on yours (maybe a bit of difference between Eduard and Roden decals?). I'm going to remember what you said and did as far as modifying the struts for a more solid fixing point.
Will look great with the rest of your squadron... but it is a rather large finished product isn't it.
Take care
Scott
