Help Please Info On My Bottle Needed

Hi

My names Chris and I live in Hampshire England.
I wonder if anyone can tell me anything about my bottle which I dug up in
1974 in Sussex.
Iv'e been told that it's a Zara seal,it's a bit lopsided eg:wobbles when
stood up and has MILLICHICH ZARA and something else that I can't make out on
the seal,it's about 6 inches tall and 4 inches in diameter but more of an
oval shape than round,it's free blown and has a pontil base.
If anyone can give me any information eg:How old and how much it might be
worth I would be very grateful
TIA   Chris
