Good morning.
I remember back when I never thought about milkies being Alley, and we did see some with diving oxblood ribbons ... I remember this in the context of discussions were people would ask us to judge from photographs if they had oxblood, and it was difficult when the ribbon dived, because the way the light played with the clear glass over the ribbon sometimes made the ox look like light was passing through it. Which stopped people from wanting to ID it as ox.
But now I don't remember anything about the ribbons other than that sometimes they submerged.
