which B3 contract used bar zipper?

I was watching "target of the day", and noticed one of the officers giving morning briefing wore a B3 with a shiny bar pull. Also, their B3 generally look more "flacid" in the arms, less stuffed like our top repro jackets, but that would probably have been due to wearing.

The M-39 Talon was used on some pre-War B-3 contracts made early in the 1941 fiscal year, such as the RW 17756, and the Aero 17757.

Thanks Andrew! I guess no one currently is systematically reproducing original contractB3s. Eastman has three, and GW occasionally has one. Why is that? is it because the fluffy sheepskin kinda hard to show discernible differences in the nuanced ways like A2 do? (other than the obvious ones such a panels and stitch patterns and zipper attachments etc? some of the "target of the day" B3 has prettty tube-like arms.
