Thanks again for all the extra input.
MHT your vase with some sort of patented process looks very interesting.
M, you have really been down this path before.
The old posts were very interesting and it seems you have an identical match to mine.
yours also has the 161 mark on the base.
My weight weighs 530 grams.
I have seen the process of someone using a lathe to make the bottom of an ice curl flat. maybe that is the process which has made the lines on the base of this weight?
Hopefully some more information may come to light.

according to a snippet I've come across Guest Brothers was an etching shop set up in c.1862 in Brettell Lane by Henry Gethin Richardson (glass industry?) and T Guest.  They'd left a set up they'd had with John and Joseph Northwood (Glass industry?) started in 1861.
Page 168 - Art Nouveau to (Victor Arwas) - I think I have this book somewhere so will have a search to see what the entire quote is later.

Uranium and non-uranium green are a time thing with Sowerby: before and after World War II, so still just green

I wonder how long the gilding would have lasted if these were used to do physical work like rubbing linen, grinding paint or applying ink? I think it would have rubbed off quite quickly from all the heavy handling, so they are probably just paperweights.

The concentric rings on the base of these items looks like they have been machined in some way on a lathe. Either that or they are mould marks from where the mould had been machined on a lathe, but I don’t think they are moulded. Flying Free’s example looks to have a small raised dimple in centre of the base which would be caused by the lathe tool not being set properly to the centre height of the lathe.

I don’t know too much about pottery but if you fire clay as thick as these, does it not have a tendency to explode as the moisture can’t escape from the middle? If these are pottery and the base isn’t glazed, they should be porous?

I think you may be right, I'll have another look in the morning
