Hi and welcome to the board. :)
Thanks for posting such lovely clear images.
Good to see somebody checking authenticity too. ;D

I think the information you are looking for should be here.
Checking the catalogues there, I can see a similar weight to yours, just in different colours, being described as being PY for Caithness.
There are articles and images here, showing fake canes and real ones.

Nice weight.

... i used a black light and nothing glows ...
When thinking about whether a weight may be a fake py example, a blacklight (i.e. longwave uv) will not always help. This is because the longwave uv reaction of the fakes is much the same as for genuine PY weights from his 1970s Harland period - which many people will see as showing "no reaction". Some people may see a very pale "orangey" colour, but again this will be much the same for the fakes and the Harland weights.

Since your weight shows "no reaction" but, as has been said, it is definitely a genuine PY weight, it is from the Harland years as opposed to the Caithness Glass period. The blacklight (longwave) reaction for Paul Ysart Caithness weights is yellow / orange (but can vary in strength of the colour). The uv reaction can also vary in strength depending on whether there is any ambient regular light and also the distance of the lamp from the surface of the weight.

Edited to add: When you said "nothing glows" was I correct in thinking you meant "no uv reaction"? Or is there a yellow / orange colouring?

WHAT I MEAN IS THE BLACK LIGHT IM USING DOES NOT MAKE IT BLOW UP LIKE A PIECE OF VASELINE GLASS WHERE THERE IS NO QUESTION AT ALL ITS GLOWING...

A black light will show more than the presence of uranium.
Selenium and cadmium also used as colourants in glass give a colourful effect too.

Ok - main point about Ysart weights is that it is the colour of the uv reaction that can mean something for dating. And it is only for early Ysart weights (pre-1962) that a strength of glow may mean something.

Generally, tho, there are no regular weights that have a uv reaction like a "vaseline glow".
