A precise history of Victor Monarch labels?

[Dischoard]

Does anyone have the exact time-frame that Victor Monarch Records moved from "Manufactured Exclusively By Eldridge R. Johnson" to "Manufactured Exclusively By Victor Talking Machine Co."? The only date I'm able to find online is 1901 but I'd really like to know the month. I've recently come across a few early Victor Monarch records and I am trying to place them in the timeline. The catalog numbers are all over the place and I've found a couple for which there is no online record. I'll post some of them here. The first one, from what I can gather, is the first recording of the Yale fight song; Boola Boola though it's titled The Yale Bola Girl and has the Victor Talking Machine credit.

The second disc is Nationality Medley, also by The American Quartet but has the Eldridge R. Johnson credit.

Per Michael Sherman and Kurt Nauck’s “Collector’s Guide To Victor Records”, the first new (VTM) labels were issued in late October, 1901.
