northernpadigger unknown...? David Rahm was known for his expertise in canal repair...other than that, clueless ?
Chris Yet another one not listed in Greer. Catawissa, PA on the Susquehanna River. Really the only way to track down info on this bottle, like so many is to either find a labeled example or find a newspaper ad..
