Share ''eagle bracket' banjo'

Hi--I posted this over on the collectors forum at Banjo Hangout, and wanted to post here as well--any help is appreciated! I  just won an ebay auction for an old 19th century banjo with eagle brackets around the rim. I'd appreciate any help in IDing this along with any ideas about the possible date. I'm attaching some pics. Thanks in advance! Jim Jacquet Olympia, WA
