I picked up this CD at the Yankee Pole Cat "On Golden Pond" swap meet today (Sept 18). It is a CD that's been on my want list for decades. It is a cool transition CD style. The top half is like the top to an American Ins Co CD 134. The threads are also Am Ins Co style. The skirt is much like the skirt to a CD 136.7/CD 158 Boston Bottle Works. The inner skirt is embossed PAT OCT 15 1872 - the date also on several Boston Bottle Works pieces. Thanks Todd for the addition to the collection!
