Buzz is now offering the L-2A with green knits. The reason these jackets sometimes have green knits is because leftover green wool from the L-2 was still around in 1950 and was used in the production of some of the first blue L-2As. Also the first B-15Cs manufactured were green and not blue because leftover green nylon and wool was still around in 1950 when the B-15C went into production. Below I’ve attached a photo taken in 1952 at Kimpo Air Base in South Korea by a member of the 335th FS. It shows an L-2A with a green collar, cuffs, and waistband. This is obviously the original configuration of the jacket and not a field replacement (field replacements entail the replacement of the damaged part only, for example replacing ripped cuffs with an available set of cuffs that may or may not match the color of the jacket). In this same spirit Buzz has created B-10s with nonstandard knit colors as well as B-15Cs in the past with nonstandard green knits. These colors are rare to find in extant jackets and photos but they do exist. So I have to stick to my original opinion that some B-10 left the factory with reddish colored knits just as the L-2A below left the factory with green knits. Buzz doesn’t just make this stuff up.
