Wine bottle holder or high coaster. Sterling grade. Very similar to products in the HaZorphim lines. Base is not plain though…punched with design that may act as drip tray for catching condensation off bottles. Mark has been double stamped. Not known to have been connected directly to the other firm, but perhaps from the same region. Or could the E-in-lozenge be some form of “Export” mark?
Do not have any kosher wine bottles, so a Brown Sugar Bourbon fat-bottle is substituted to demonstrate the diameter, which is wider than a common wine bottle, at 3 3/4 inches here.
