Just picked up a nice "SIDNEY" 3 leg spider with a number 8 on the bottom, The bottom design looks like it was also designed to fit in a stove eye. Here are some pics, Someone painted it but overall it does not look too bad, I can see some rust scale in the bottom that was painted over but the bottom looks solid and sounds solid when I tap gently on it. The "SIDNEY" is set at 1/2" below center of the pot.
My understanding that the Block letter "SIDNEY" marked pieces were after Sidney Hollow ware sold to Wagner, Is there any way to accurately date a piece like this, My guess is pre 1900 but was Wagner also producing Wagner marked pieces and still producing Sidney marked pieces at the same time.
