Hi Roy & Greg... I too have had several of these Windsor vases. Most of which like you say have only frosted ladies. I have had one all frosted example only using amber glass... that I considered to be of a later date. I have also seen them in Jadeite glass and streaky grey. Whether these are pre-war or more recently made from original moulds, I cannot say. Recently too, aqua-blue examples are showing up here and there. I do know that three sizes were also produced, one of which was twice the size of the largest that we mostly see. I once owned this huge piece and can now kick-myself for parting with it back in the 1970s. More to the point, it was maker marked to its underside inner base, most of which was missing due to a chip being present, but the remaining letters "DER" were moulded and evident, which in itself is uncommon for Walther. I have never forgotten the vase. It was Walther blue, with frosted ladies and was taller and wider than the Schmetterling pattern. John
