Sure thing.
I know Champ has horsehair because in addition to Ron saying so, he sent me a dug Champ with it. But that was aqua. The transparent swirls are really really hard for me. But also in the dug Champs Ron sent is a blue transparent swirl which looks much like yours in color and texture. No ox though.
By texture I'm thinking of the look of the white. Nice and meaty, with a textured underside, and that little groove running along the top of the ribbon. Do you see what I mean about the groove? It's very visible in the bottom left view here:
It's in my dug champ, and I think I've seen it mentioned in other Champ ID's.
But it wouldn't be the first time I'd associated a feature with some particular company and come to find that others did it also. So, DID Alley also have the little valley running along it's transparent swirl ribbons?
Well, whether or not they did, my blue Champ swirl looks very much like yours in the colors and quality of the glass. Not as busy, but still very similar.
