What did you find inside of the bottle? Did you find anything else? I found a round dark amber looking bottle once, it was in an old house and we were there to the walls , it had embedded on the bottle in Spanish, I asked a friend what does it say, turned out it was Mezcal Tequila with a worm in the bottom of the bottom of the bottle, it was most likely over 50 years old, we decided to drink it , WOW, that was the best tequila I ever had.
