My next match-up finding is for the Lakota double trailer ceremonial bonnet with beaded firecrackers cat # NA.205.14A/B from BBHC (Cody Plains Indians museum, the Catherine Bradford Collection).

I found few early 20th century photographs that show different Lakota Indians wearing this bonnet. Here are links to download high-res photos:
