As little is known about this trailer, we are going to label it as the "Tharnco" trailer due to the identification in the last photo below. More than likely, this trailer was either built or sold by the Tharn Co. The only reference found on the internet, is to the J.S. Tharn Co. in Philadelphia PA. from "The American Architect and Building News, Volume 84" in Google books. If you have any info on this trailer assembly, feel free to drop me a line and tell more.
