Unknown Sugar Shaker

This unusual sugar shaker is unknown to me. Its is an unusual green fading to clear at the bottom. Then it has a extensive etched pattern covering a good portion of the shaker. The pattern in the glass is a simple paneled pattern.
When I bought the shaker, it did not have a top but was obvious that it required a two piece top. I used this simple two pece top for now.
I have never seen another example.
