Hi Ivo,I have a vase similar to yours,same size,amber colour with all the crazing on the surface.It flouresces brilliantly under U/V light.The only difference is, mine has a galleon in full sail on the front.I too do not know the maker or the year of manufacture.Kind regards,Kay.I have sent two photo to yobunny gallery but unsure of how to attatch to this message.
