I agree with John that the item itself is of more interest than knowing the maker.
But for reference, having found a camera that works and also finding some daylight, I have provided some photos of my Webb vase with the cameo-fleur "tulip" design. I have tweaked the images to enhance the details of the cameo work, but the background is still rather grey, even though it is a large sheet of white art paper!!
Photo 01 shows the vase as a whole + the signature from near the base
Photo 02 is a view of two sets of tulips - which is a repeating pattern
Photo 03 gives a closer and more direct view of one section of the pattern
photo 04 shows how the leaves and stems are worked from the edge of the base
