Hi Frank,
The Scottish Glass Society weights with the "A" & "H" canes are not Caithness,they are my personal work.If any "One-offs" have a "CG" cane then they are designs I made for Caithness.
I am curious to know how these weights came to be on the market as I know the person I sold them to was always adamant that he wasn't going to sell them;I do hope he hasn't given up collecting for some reason.
P.s I am busy working on designs for this years SGS exhibition,which starts in July at the Collins Gallery in Glasgow.
