Do you know I can't remember how that one turned out in the end. I remember there being a lot of discussion about it (Walsh v Richardson maybe?) but can't remember what it was eventually id'd as.
However, the pattern on yours looks like an unopened tulip and leaves or something doesn't it?
Just that the technique is similar but yours, instead of being opalescent with the thicker parts showing as whiter and therefore showing up the mold design more on the opalescent pieces, is green to clear but still mold blown in a similar way. Did I explain that badly

ah well, hopefully you know what I mean.
