1978 Revels commercial
Originally, Revels had orange creme, coconut, toffee, or peanut centres, along with Galaxy Counters (Minstrels minus exterior shell) and Maltesers. However, the coconut centres were later replaced with coffee creme, and the peanuts with raisins.
Galaxy Counters were initially available as a product in their own right, but since their discontinuation they were only sold as part of the Revels selection. In 2010, however, Galaxy Counters were relaunched under the Galaxy brand.
