N-2, N-2A, N-3A, all original with fur ( in the hood) and coyote trim...Dry cleaning only, but in a place specialized for fleece and fur cleaning...always came out perfect....Same with my WW2 B-10, B-11 and B-15C....professional fur and fleece dry cleaner only...No risk paying cheap cheap just to ruin such a jacket.
Back when I got my N-3B, something crawled out of a pocket, so I took it to our local dry cleaners, who were most concerned that the leather bits (around the drawstring holes etc.) might be vinyl and not leather. I assured them that the USAF was not using any vinyl in 1965. Came back fine.
