Wine Pourer, Decanter Holder.
This is clearly a relative of the wine coaster, which I was calling a wine decanter holder thing, and now learned it’s called a coaster via this antiques website. So that puts it squarely in the garage sale camp. Although I suppose it’s possible they snuck into the apartment independently.
I forgot to look for a mark. But I suspect it’s also silver-plate. It’s quite sturdy, and we don’t own the glass decanter it should presumably go around. So without its glass mate to properly function, it earns the status of uselessness. Obsolescence almost goes without saying, when was the last time you went to a dinner party and such a pourer was used?
Status: Not mine, so no comment. Although it does partly make me think of Poirot, so it has a charming imprint.
