Okay, the size is way out for 9548 but I can't see any others with that sort of shape. I know how difficult it is from photos but the colour doesn't look murky enough for Shadow Green. Also a nagging questionmark in my mind is the thickness of the glass, the WF soda I have/had was thinner than that.
Sorry not conclusive I know, I'll keep my eye out in the catalogues as I browse.
