[78-L] Victor number puzzlement

a couple of numbering series I've never seen before..30000 and up (ten-inch
purple label) and 37000 and up (10 inch purple label). Qu'est'ce que c'est?
Also, it lists the post 1942 ten-inch popular black label series as "20-1400
and up". Thought it started at 20-1500. Did they go back and use some lower
numbers for a special series at one point?

AFAIK, Victor's series started with 20-1500; I've never seen (nor do the
"Abrams Files" list) a lower number...?!
