You are very welcome Christine and I know what you mean about finding non-paperweight Caithness.
I spent hours looking on the Internet until I came up with this site.
I know the prices are really up at the top end, but for reference, I thought it was great. Maybe it was just because the weights that I have are Club Collectors weights, but this was the only place I could find them. I didn't even want to find out about them for their value, because I intend to keep them, just to learn a little more for myself. (I can't really afford books yet)
I decided to buy the Mooncrystal weight, the price was too tempting.
