Attribution help needed.

Could someone in the know help me with attribution on this bust half? I've tried to match it up with the pictures of the 1829 bust halves on the Russ Logan collection auction site, but don't think that it's any of them. Thanks.

It's an O.115, which is an R1. It also appears to have been cleaned.

i guess that would make sense...the O-115 on the Logan collection site is an O/C error and I couldn't see many of the details. Thanks!
