Big Band - Small Band

Okay, I understand that Victor re-used or appended to matrix numbers when the same song was recorded by the same artist, even at a much later date.

However, I'm having trouble interpreting this specific situation:

I have a Canadian Victor #17231:= Victor Orchestra: Anvil chorus / Pryor's Band: The forge in the forest.

Using the Victor Encyclopedic Discography ( http://victor.library.ucsb.edu ), I see that one version of that disc was recorded as [Anvil] Mx B-4475=5 (1907-07-10) / [Forge] Mx B-1287=5 (1905-11-23).

These sides were used in other discs, and had their first U.S. combined release in February, 1913.

Then what appears to be a new edition of the disc was recorded as [Anvil] Mx B-4475=7 (1913-02-06) / [Forge] B-1287=6 (1923-07-24), and it was offerred for another three years in the catalogue until it was dropped in 1926.

Or were the new recordings just dubs? Or am I misreading this page completely: http://victor.library.ucsb.edu/objectDetail.php?id=11685

Why would the Victor Orchestra re-record "Anvil" in the very month that the disc had just been released?

Do the labels from my copy give a visual clue as to which edition it is?
