Bolig lists the A-side composer as Richard Eilenberg. The label does, in fact, read E. Eilenberg.
The ODP and Bolig clash on this disc. Bolig's listing in the Victor Black Label Discography has the mx numbers reversed from the assignments made in the ODP. The recording dates and places follow suit, so that everything is reversed except the titles and composers.
Bolig's assignment is intuitively more probable since it lines up the lower matrix number with the earliest date. Both takes were numbered 1 or 2, which makes it more likely than not that they were each made at the first session in which they were attempted, and not at a subsequent re-make session.
All that being said, experienced discographers will tell you that numbers are sometimes taken out of sequence for various reasons. One of the more common occasions for such a departure were "field trips, where a group of matrices somewhere in the upcoming sequence would be reserved for use on the road. The reserved matrices might end up being used earlier or later than they otherwise would have been and thereby thrown out of chronological sequence with the surrounding numbers. One of the two sides on this disc was cut in Washington, which makes it a candidate for such treatment.
