I think extending the title to include all the names is an excellent idea m... this is an intriguing subject.
I saw the smoke colour vase on eBay , and wonder if the Dartington name is being used as a result of urban myth?? It will be interesting to note any reply here for future reference.
The Lasisepat vases on Huuto ( Now ended) were referred to as 'Metsa' meaning forest, but I have since seen others listed as 'Metsa' that are quite different.
In fact PX you made a link to this thread:
http://www.glassmessages.com/index.php/topic,40060.0.htmlwhere you say the square bowl is Lasisepat Mantsala 'Metsa' design, yet I found one shown further on in the thread that I added that had the Viking label. So was the Viking label added to the second one, or was the Lasisepat one originally a Viking bowl with the label removed???
I am not trying to be argumentative here, just want to show how easy it is for any of us to be carried along by the belief that an item is made by a glass manufacture just because it has a label, even a signature can be forged.
To some extent I feel a sense of responsibility for perpetuating
what may possibly be a further urban myth, because for a long time, when I saw a Lotus vase listed as Dartington Frank Thrower, I messaged the seller saying it was actually A Lasisepat Metsa design votive made in Mantsala with all the info I had gleaned at the time. It may still be true, the design may have been sold on, but we have no record of any of that.
So an illustrated carton showing the contents is invaluable in helping to positively identify the provenance of an item. And that is all I have tried to do here....share with you all, the ones I have, that have boxes illustrating the contents clearly, with Made in England on them.
I am sure there will be more to come in time. As they say, 'The thick plottens'!
