The John Savery's Sons w.i. is not from the Savery & Co. (Peleg Barrows Savery, John Savery's Brother) of Philadelphia, but made by John Savery/Phoenix Works foundry. located in Jersey City, New Jersey. The New York marking is referring to their Office and Warehouse location. The marking as shown was used from 1853 up to 1888. The # 4 (6-7) is the hardest one of the four made to find. (they were made in # 1,2,3,&4). There were two variations of those that I'm aware of, and the one shown would be the latter variation, so likely 1860-1888. The earlier #4 variation was of a different font, etc.(and the support frame was different as well). Savery & Co., Philadelphia was an entirely different foundry, owned by John's Brother, Peleg. We have their timeline in our PDF files. My interest in value is more from a Historical aspect, but if in good condition/no issues, the # 4 w.i. could be in the $ 400-450 range (especially where the prices have been as of late). Seems I have seen those sell from a low of about $ 275, up to $ 400 +. The Foxell & Jones, not much value unless complete with the support frame in my mind.
