Need help with bust half attribution

Blackhawk

I've been looking at this one for awhile and believe that it's the O-104, but there are a couple that are similar. Anyone have other ideas.

I agree that it is reverse B (102 or 104) since there is the tine off of the tip of the eagle's right wing. But I think it is obverse 1 (o-102) based on the alignments of stars 7 and 8 to the cap. The final diagnostic is too fine for me to see in these photos, but if there is a very fine die crack running from the upper lip through the lower lip and then to the chin (on a curve), then it is definately an O-102. Unfortunately the Peterson diagnostic for the 104 is on the ribbon below the clasp in a place with heavy enough wear on this coin to obliterate it, but the star 8 to cap alignment looks wrong for a 104 to me.
