Well done!! What a beauty!!! I have no doubt that it is by Paul Ysart (but the specialists will confirm this attribution, I hope). He has done some pedestal weights but they are rare. I have never seen one in the flesh (so to speak) and I never seen one with a fountain (which is what this is, I think).
Because of the colour of the glass, I suspect that it is Moncrieff period (I would suggest pre-war rather than post-war but it is difficult to be sure without the short and long wave checks).
You are a lucky person! I would love to own it.
