Not sure when this was made or what set it might be part of. On the bottom it says--American Silverplate Co. This is around a circle that has the word QUADRUPLE in the middle of it. Below this is the number 615 and below that is COFFEE. I tried to shine and clean this up as much as I could. Might have been used long ago and was possibly burnt. Also, this is the lid that was near it when I found it. Not sure it belongs with it, because it shows an attachment for a hinged lid. Four feet that are indented into the pot almost like the bottom rounded part of the pot is bent in. On the one side it has a big "W" stamp or a "M" in OLD ENGLISH. Not sure which one but leaning more toward the 'W'. Thanks in advance for any responses!
