Here's a hand-written banjo arrangement for St Louis Rag. I got this from ABF and the anonymous transcriber has indicated that the arrangement is by "F. VE". I guess that's Fred Van Eps. I'm not aware of a recording of F.VE playing this solo but there's a good rendition by Vess Ossman on the cylinder preservation website.

there's also a slower home-recorded duet rendition from 1910 by John Cunninghame and Richard Tarrant Bailey Snr. on the out-of-print Tarrant Bailey Collection CD.
