According to Hajdamach, this could be Webb's "Gay glass".
The bullseye pattern is part of this, although the pics illustrated in the old advert photographed only shows bullseye in Evergreen, the blurb says Old English Bullseye was made in all colours.
I think you may have a piece of Sunshine Amber, and it would be from the '30s.
It's kind of hard to tell from your pics, Keith because Bullseye is much thicker than the other patterns. I'm used to seeing finely blown Sunshine Amber, not thickly blown stuff.
But
something in your vase "sings" to me.
Perhaps it was the green hints, perhaps it's the actual sunniness of the Sunshine Amber?
Or just a general shrieking of top quality?
