Where I live in MD I have 2 creeks that meet out on the back of my property and we are always finding old bottles that wash down the creek so I was hoping to find a place where I can maybe get some identified. We found one yesterday that was a Chesterfield Brand bottle made in Havre-de Grace. It had a patent date of Dec. 29, 1925. I am unable to find out anything on this company or this bottle.
