We have a mark on the bottom of a silver teapot that we can't ID. The teapot has what looks like leaves or petals around the bottom and a leafy handle with ivory-looking rings at the bottom and top of the handle. The top of the pot has a wooden knob with a silver flower accent on the top. On the bottom of the pot, the mark has what looks like a tiny hammer and triangle or piece of material or flag in it. An inch to the side is a stamped "Z". If anyone thinks they might be able to tell what it is, please message me and I'll send a picture. We're not even positive it's American. We found it with an Evans Case Company Silver Teapot (unknown year) in the trash.
