Bob Gillette played with Bix Beiderbecke & the Wolverines, and the New Orleans Rhythm Kings.
I just noticed that it looks like he is playing a 5 string banjo with the 5 string removed.

In 1924, the Wolverines recorded a Hoagy Carmichael tune called “Freewheeling”. The band liked the tune but not the name. Bix said it reminded him of a Riverboat. Bob said that the rhythm had a shuffle to it. They renamed it the “Riverboat Shuffle” which has gone on to become a classic.
