Original, early M43 Field Jacket, size 40R, mint condition. This one has only the most minimal signs of wear- a small stain (1") on the inside and a crease in the collar. It appears someone wore this a few times perhaps to go out to dinner.
370C, November 1943 contract, which pre-dates the Pattern B amendment meaning this is the smaller cut, same as the 370B's made a few months prior. Thus, this is from the second batch of M43 Jackets.
