I have photos in my database of two Side B labels. One has the 11495 mx, the other the 11510 mx. I gather that somewhere along the line they realized their mistake and corrected it.
From the YouTube comment: In what I consider a very unusual occurrence, the Art Landry composition Rip Saw Blues was released on Gennett under two numbers, 5255 and 5171, with different couplings. His first recording, a waltz entitled Dreamy Melody, was recorded on February 12, 1923, but not released then. A very odd one-step arrangement of You Tell Her - I Stutter was recorded on June 1, 1923, along with an unreleased arrangement of Rip Saw Blues. Then Rip Saw Blues was recorded again on June 15, 1923 and coupled with You Tell Her I Stutter on 5171 and Dreamy Melody coupled with Rip Saw Blues on Gennett 5255. As that cliche says, "Go figure!"
The comment is not quite correct because Landry's first recording, "Dreamy Melody", was actually released then, on Gennett 5052-A (B-side by Sam Lanin's Famous Players) in April 1923. Consequently, Gennett 5255 was a coupling of two previously released Landry sides, something not so unusual then and now.
Apart from this I can't believe that the first recording of "Rip Saw Blues" from June 1, 1923 (mx. 11495, denoted here as unreleased arrangement) was ever used for Gennett 5171 which came out in August, so the second recording of June 15 (mx. 11510-B) could be used without problems. The mistake was probably down to the fact that the label printers got the wrong information.
... what is especially strange as the same matrix (11510B) of "Rip Saw Blues" seems to have been used on a later Gennett record with cat# 5255, which was released in Nov 1923 (A-side: "Dreamy Melody").
This one here was announced for the bulletins (record company catalogs) of September in Talking Machine World of August 15, 1923 (p. 164), i.e. actually released in August 1923.
Label to side B bears the matrix number 11495 which signifies an earlier version than what's on the disc. Matrix shown here is in the wax; it is unclear as to whether 11495 was released. Abrams data says yes; Rust's "Jazz Records" says no.
