Well, I'm just going by what Bob McGrath has in his 2nd edition of R&B Indies. He starts out with the red label giving the owner and location, then, when he gets to the blue label, he says the info for that is that same as the one above, therefore, from what I can tell, it's the same label. I don't have any red ones, so I can't compare them with the blue ones, and I only have one or two blue ones, but, it looks to me like they have almost the same numbering system except that one generally starts with J.P., the owners initials, but both use A for one side and AA for the other.
