The guy at the Swapmeet told me he got this out of 100+ year-old Catholic Church in San Diego, and that it was for Holy Water.
It is copper (amazing patina), about 16" in diameter, and would hold close to 3/4-1 gallon of water.
The lid has crosses, and possibly crowns! It has two ornate handles, and it has a rounded bottom, with a bit of flat so it can sit on a solid surface.
It appears quite old, probably handcrafted, no hallmarks I can see.
I looked online, and nada! There are some braziers for burning incense that seem somewhat similar, but there is no sign of smoke...but, then again, it looks like it hasn't been used in some time.
We were stopped by half a dozen people on the way out commenting on it.
I paid $40 for it.
Anyone have any ideas? It seems wonderfully unique...
Thanks in advance!
