Peter, sorry I did not have your email address but I saw this posting from another CR member and your name popped into my head. Look at this ebay auction # 180111423087 and you will see what I mean. There is a text description among the photos with the Bruggemann name in prominance. It is an old Columbia bike from the 1800s and the story is pretty interesting. Not sure if you are related or if the spelling is exactly the same but since I know you are a CR member and into bikes I thought I would give you a heads up on this.
