Hi again all,
Hands up everyone who thought we had finished with this topic,

I now have a collection of three of these "Historic" ? weights, all slightly different.
Here are a couple of photos of the new one,

It has a small air bubble above the inblown moon surface which is not on the Perth factory ones and is marked to the rim, CG 19/500. The glass is twice as thick as on my other two Moon Landing weights both of which are from the factory at Perth and are of a limited edition of 1000.
It's also of a different colour again, this time being a smokey brown.
I believe this weight to be from the Caithness factory at Wick, but as usual I would welcome others opinions and comments.
