Where the vase is concerned, it's definitely French.
Within our bulb vase club we have all the Vilmorin catalogues dating back to 1860 and so we can follow exactly when and how this vase was offered, first enamelled, then amberina, then plain with cotes venetiennes (yes Frank, here we go again), etc. till 1931.
Which factory made it, a bulb catalogue never mentions but as the enamelled ones are offered by Legras specialists on the big French fairs and when you study the flower enamelling on their other vases, there is no doubt who made it. So it's likely they continued with the amberina and plain ones as well.
Vilmorin offered 48 different models of hyacinth vases between 1860 and 1940 which gives us a lot of study material. And when you find one with a Baccarat sticker on it as we did last year, the whole club is up in arms! All I can say is that one bulbvase collector out there is going te be very happy to add Ivo's unusual vase to his collection.
My glass knowledge might be very limited (but with Ivo living around the corner, that's alright) but I do know my hyacinth vases.
