Thank you Pamela that's a fantastic find, I did look for it on your Pressglas site but was distracted by the proliferation of postings originating from the U.S. and forgot to look in Masterbuchs.
As Ken says It seems most likely that you've found the origin of the design and I would be more than happy to think that I have an original item, but am sceptical because of the crisp nature of the base and lid rim areas. It's always possible that this was kept purely for decoration though, and I haven't seen another green version so far. As they say, 'the jury's out'.
As a novice pressed glass enthusiast, I'd very much like to take this chance thank you for your work on Pressglas and Masterbuchs and for making them freely available. I can't stress enough what important and fascinating resources they are.
