This well and tree tray came out of my grandmother's kitchen. My guess (and that's all it is) is that it might have been a wedding gift - she was married in 1926 in New York City. There is no writing anywhere on the tray; just the four marks shown below. I have looked at pictures/lists/indexes on the internet until my head hurts and my eyes are blurry! Is there a kind soul out there who can translate these hallmarks for me? Thanks in advance for looking!
