Thanks for the info. I wish now I had bought it. If anyone is interested it was in the Quay Antiques Centre at Topsham. Can't remember which floor. It is made of jade glass and consists of a central stand around which is a detachable collar with three bowls, only one of which had a lid. The only other rotating condiment set I know off is the Jacobean one which holds two oil bottles, mustard jar, pepper and open salt.
Also at Topsham I bought a Clarke's No 17 Flower circle base (no shade) and a Price's candle holder. Both of which I will be taking to the Cambridge Glass Fair.
Best wishes for 2011
