A few bits of info from Buzzfile about S.M. Frank & Co., makers of Kaywoodie, Medico, and Yello-Bole. The company was founded in its present configuration in 1991, but the history goes back over a century. It is located in New Windsor, N.Y., about midway between New York City and Poughkeepsie on the Hudson River. Annual revenue is give as $935,663, and the number of employees at the location is 8, in a facility of 15,000 square feet. I can't vouch for the accuracy, but this at least visualizes a little about this major name in U.S. pipe making.
