Yo, Daywalker:
I have a partial sheet from the old P-39 kit that includes the sharkmouth, rooster door emblem, Brit serial, "Hell's Bells" lettering, U.S. Army and the tail number. No stars. The sheet is, I believe, from one of the earliest releases of the kit, so you'll probably have to use decal restorer or scan it on your computer onto a blank decal sheet, whatever.
Anyway, I've just had it sitting around for years, so I can just send it to you. Can't think of anything for trade. I'm new to the forum business, so how do I get it to you?
