Thanks to Frank "Steamhead" Wilsey for finding and scanning these pages. He writes, "These scans are from the Walworth Manufacturing Company's 1892 catalog, which I recently received. This same catalog is referenced several times in Susan Reed Stifler's book, The Beginnings of a Century of Steam and Water Heating. Walworth was selling quite a few H.B. Smith products at the time, including Mills boilers and various Smith column radiators, as well as other standard types of column radiators. This set includes Walworth vertical pipe radiators, which look a lot like Nason radiators, and a dining room radiator they also sold at that time."
