Is this a snuff bottle or a perfume bottle ?

I bought this at a pawn shop 30 years ago because it looked like a perfume bottle. It has a cobweb engraved on the front. It looks like it used to have possibly a chain connected to the lid. It is about 2 inches long and 1 inch wide. Looks like it made of brass and has a bottle inside with some cork still left. I took to an appraiser 20 years ago and he couldn't put a value on it but said he'd offer me $350 for it. I've never seen anything even similar too it.
