Am sure you are both correct re the original quality of the gilding, some of which remains although doubt as bright though - however, glass wise this example is otherwise quite basic in its manufacture, with noticeable mould/flow lines showing. Have looked again at Ivo's descriptions of backstamps etc., for Moser, but still don't see this exact one, many of which are oval as opposed to round as here. The lack of the word Czechoslvakia might indicate earlier than 1918, and use of the word Karlsbad looks to have been an indication of earlier manufacture. It stands a little wonky, and you can see it's not quite 'round' at the collar/rim Am I correct in thinking that this floral/swags sort of enamel decoration was more of a late C19/early C20 style?
