Thank you for this information. If I could bother you again, which companies does Tom mention? I'm still surfing the web trying to determine where this bottle came from. You said the bottle is from the latter part of the 20th century, then may I ask this one question? Why are there so many man-made? deformities in this bottle? Or was it just a sloppy job on the bottle-maker or machine producing it? Thanks again for your time. M.Fahrney
