I just finished the Hulu series Catch-22. It is my favorite book, and the TV adaptation is excellent... and since I have a 1:48 B/25 waiting to be built (I got it years ago because of the book), now I wonder if anyone is making decals for Yossarian's plane in the series.

Kits World decals makes a couple of sheets for Catch-22 B-25s (from the original movie, I believe):

I don't remember which one was Yossarian's, but I'm betting it was one of these.

HTH!

Here's the aircraft they used for the filming

It belongs to the Tri State Warbird Museum in Batavia Ohio.

I don't know any specific decal sheet for this aircraft but since the squadron is fictional, you'll need to piece the markings together from generic sheets
