Thanks again, Rick, it's not really brown, looks a bit more like a blackish contaminant, and there's a fine streak of yellow slightly separated from the main patch there too, where the base glass shows through a bit, which adds to that appearance . . . I think.
And thanks to you too, Jim. I agree that the Victory base should be bubble-free. And I had always thought Pelt made this type - I don't think I've ever seen similar attributed to Kokomo, but it wouldn't surprise me too much, and I am in Indiana so . . .?
