When I published that post I was fairly certain I knew exactly what the antique’s purpose was, but I thought it would be fun to see what my readers thought.

I truly believed that this silver piece was a butter server. One would put ice in the bottom section, place butter on the round piece, and lay that atop the ice filled bowl. The dome could be raised to serve, or closed to cover the food. A small spreading knife could be placed in the attached holder at the bottom. All very elegant and old worldly.

Regardless of its purpose I’m fond of my estate sale find. And this morning as I was decorating my home for Halloween, I noticed someone else had taken an interest in this antique:
