This is a large antique brown apothecary bottle. It was manufactured by Central Scientific, who was in business from 1900 until 1974. I am not sure the exact age of the bottle, but know that it dates to after 1909 because they were not called CENCO until then.
This bottle is in excellent condition, and it still has its original label and metal lid. Take a look at the pictures, and if you have questions, please e-mail.
