I was in the confectionery business for 15 years and worked for Chocolat Tobler Meltis later to become Tobler Suchard and after that for Swizzles Matlow.
It was a great industry and the unofficial swap meets after Trade Shows were legendary!
There was Cadbury, Mars, Rowntree Mackintosh, Nestle, Trebor Sharpes, Clarnico, Barretts, Bassetts, Duncan (Walnut Whips), Jameson's (Raspberry Ruffles); didn't buy sweets for years!
