Old Indian Trading Post Belt in Aluminum with Stamping Whirling Logs

Old 1920s Indian trading post belt with 9 "concho" panels and a buckle of aluminum. There are several different designs on the panels.  The buckle has a large Thunderbird and the very collectible whirling logs that were discontinued around 1932 I think it was. 

The panels are connected with brown leather lacing. It is 26 1/2" long and 1 1/4" wide. Very collectible piece. I have never seen one before.
