1880`s Boston Whiskey, Lyndeborough Glass Works?

Description

Here we have an 11 1/4" tall orange-amber 3 piece mold unembossed smooth base labelled whiskey for "Pure Liquor Put Up By The Cushing Process Company Ira B. Cushing M.D. President Boston, Mass." It is in excellent condition with no damage or staining. The glass is too perfect looking and almost bubble free to be from Westford or Stoddard, Lyndeborough, or Lyndeboro, Glass Works to me would be the logical place for this to have been made, but this is only an educated guess, it`s still a great looking bottle no matter who made it!
