Wondering if anybody is able to tell the age of these pieces? All were found on the beach in Angola, New York off of Lake Erie. Pictures 4,5,6 are all the same piece. It is marked "8Oz" and with the number "82". It is more of a rounded rectangular shape than completely round. Picture 3 is the bottom to what looks like a very small rounded rectangular bottle. Only letter that is recognizable is "Q". Would like to know more about all of these if possible! I would also like to know what they were used for if possible! Let me know if more pictures are needed!
