English or Bohemian Applied Glass Vaseline Large Bowl

Hello, this is a interesting Vaseline bowl which has a lot going on. First off the Hand Applied Glass Threaded Top, along with the Hand Applied Feet add a lot of character. The main body of the bowl is bulbous and was made with more bone ash giving it a more opal appearance than both the applied glass at the top and base. This bowl also has a rough pontil that has no polish. I believe this bowl is ether English or Bohemian, I know though it is very interesting and very old. This bowl measures 6 inches across, and 5 inches tall. if anyone has any comments or information please feel free to post them! Thanks for looking!
