Thank you very much, John!
I checked the makers mentioned in the thread you linked to, but nothing similar popped up...
I know -- jugs are difficult, and everybody did crackle glass

Still somehow I had hoped the amber Uranium glass would point towards a maker / region / timeframe.
(And searching google, there doesn't seem to be
that much of it around).
But as Christine (from Uranium Towers) hasn't responded, it seems quite difficult to attribute...
