I've never seen such perfectly formed letters in any slug-plate bottle. Even in more evenly formed letters in many slug-plated bottles I've seen, the letters were more rounded than flat. The lettering on that bottle appears to have been formed by a draftsman. Another point that causes a bell to go off is the color and depth of the pontil. It's a beautiful bottle and I hope for the buyers sake that at least one other can be discovered. One of a kind, especially where the object was mass produced, is rare to find, and the question of "is it real" always is in question.A friend of mine once made me a personalized Cure bottle by taping off the letters & burning the glass with acid & then cleaning it . It looks awesome . I hope someone has seen one or dug one before . Slugplate & letters look very unusual .
