Dear Elizabeth-The Overmyer Mould Company was founded by my grandfather, Chester Peter Overmyer, in Winchester, Indiana.Over the years, they manufactured glass moulds for the likes of Anchor Hocking, Coors Beer, Coca Cola, Avon, Ball Bros., etc. My father, C. P. Overmyer Jr., was president of the company in the early fifties when it was the largest independent mould company in the world. After my father left the company, it eventually went into bankruptcy in the eighties for lack of direction or restraint by its board members.The bottle that you have is a fifty year commemoritive. The company was sold in the ninties, I think, but is no longer called Overmyer. My father lives with me and my husband here in Casper, Wy.He is 92 years old! I hope this helps a little with your bottle.I am curious to know from whom you purchased it.
Sincerely, Hattie (named after my Grandmother, Hattie Collins Overmyer)
