I got 2 of nearly the same bottle (I am almost sure they are 3 piece if I remember correctly)! According to the tag at the antique when I bought them, they were found in an 1830's shipwreck near either Bermuda or the Bahamas, I forget. The dealer had around 2 more but I never got them, I regret doing so because they only cost 15 dollars each. I would say yours is probably the same type as mine.
