It's worth mentioning for reference for when the listing vanishes from ebay, that the images in the ebay listing linked above actually show the same marks as the ones Pete shows here, i.e. Waverley Made in Scotland, not the Edinburgh mark. The reference to the Edinburgh mark is in the accompanying text where the seller says the mark is the same shape and font style as the Edinburgh one, but his marked glass says Waverley instead of Edinburgh.
Pete, could you also ask the seller, if you do contact him, if we may add copies of his label and mark to the labels collection for the board please, with credit duly given, of course.
