Comment by TheJudge:
I've gone through them and I think I've caught all of them and amended the cat#s accordingly.
Comment by Mike Gann:
Okay, we'll leave them out
Comment by xiphophilos:
I respectfully disagree, The N for New York, C for Chicago, and L for Los Angeles recordings that appear on Brunswick labels between 1930 and 1931 have nothing to do with the catalog number. No one else adds them to the cat. nr. either. See, for example, the DAHR entry for this release at
