Cdraw1998's Buffalo Bell can be downloaded through 4shared. You would have to send a note to the creator on deviantART for the link. This model is based off of the mascot for the Japanese Professional Baseball team, the Orix Buffaloes.
This is the only model of Buffalo Bell to be released, plus the second model to be made for MMD. The first being J-Fujita's, which is entirely based off of the actual mascot suit, but has yet to be released.
