Hi--any help with this mark would be greatly appreciated. It comes off of a large, two handled tray with a pierced outer rim to an acanthine border. The tray is quite substantial, about 130 ozt. It either appears to the an unknown symbol/the letter B/a clover leaf?/an unknown symbol/fleur de lys OR it could be an unknown letter/letter B/ & (ampersand)/ unknown letter/ fleur de lys.
Any thoughts or resources for further study would be appreciated. I have already used Jackson's and Tardy as well as World Hallmarks from the Hallmark Research Institute in addition to this site, which is always most helpful.
Thank you in advance for you help!
