Well found Keith - there are not many of those to the pound!
I have now nailed down the correct name for this pattern: Mesh. While this contradicts the names previously given in Chance Expressions, this was due to the information being available at that time, and I was relying on the memories of former workers - often very good, but fallible. This is corrected in Chance Additions.
I dread to think how many I have - possibly three figures - but only a few choice ones are on display, like Cut Pearl and the other Intaglio models.
