Hey Niels,
Aeromaster made two decal sheets with 386th BG Invaders on them:
48-160 WWII A-26 Invaders Pt.I
48-161 WWII A-26 Invaders Pt.II
Unfortunately, these are out of production. If you want to try and find one of these sheets, try going to
Hyperscale, clicking on "Discussion Forums" and then on "Plane Trading" and make a post.
The ProModeler release of the A-26 kit was the A-26B and included decals for the 386th aircraft that's on Aeromaster sheet 48-160.
For some photos of 386th BG aircraft, go to
Web-Birds.com and scroll down the left side of the page until you see 386th BG. There's mostly B-26 Marauders here, but there are a few shots of Invaders. The profile at the top of the 386th page is "Stinky", the aircraft on Aeromaster sheet 48-160 and also on the ProModeler kit sheet.
Fade to Black...
