Brass Glass Ashtry no markings

Ashtray is roughly 3in across and 1in tall.

The base/bottom and 3 legs seem to be made of brass.

A concave piece of glass is the top or inside of the ashtray.

Under the glass is an ornately embroidered floral pattern, stiched

onto what looks like silk.

I have spent many hours researching this item and have found three others nearly identical. 

The flower patterns are different.  One in Australia, the others here in the US.

I bought it at  Goodwill/Junk store for less than 5 bucks.

Any info would be appreciated.

Thanks for looking!
