Hi Steve; no I bought it at one of the UK National Shows, so it was dug in UK. I don't know of any dug out here, though there might well have been. Will check around.
I emailed Walter Devault about my Turlington bottle. He felt it was English , but could be a countereit. There is no way to tell for sure. He felt it dates in the 1780 to 1810 range, but hard to be exact about that. He told me the Turlingtons came in 2 sizes and mine was the smaller size. He currently has a collection of 150 Turlingtons. Maybe, we can get him on here to aid in our discussion. He sent me a some pics of some old clear Turlingtons and an 1750 Turlington.
