Re: Fair, Day & DeKlyne , the information on this foundry is very limited.
We know they existed in Knoxville, Tenn, 1880 - 1890, and that is about it. Tennessee has not yet made historical corporation records available online, so maybe someday soon we will learn more, but for now that is about it.
As you photograph your items, be sure to frame the entire top of the item, including the handle(s), and the entire bottom of the item including the handle.
Good pictures are critical to identifying a piece. We look at the markings and much more. :)
