Just wanted to jump in and point out that the lot numbers are each cut with notably different sleeve/shoulder patterns. I just got a 401 and discovered that it's cut & sewn to fall off the shoulder quite a bit. It makes for a more relaxed, less fitted look than my buzz rickson's, which has narrower, set-in sleeve pattern . The warehouse "freedom sleeve" models look to have more of a hybrid set-in + raglan thing going on that gives a more fitted looking shoulder.
