We have a cigarette case that seems it came from Wales by the inscription, but the Hallmarks are so small and plain we don't have much to go on. Each side of the case is marked and appears to be "CGEC" but the G especially could be something else. The inscription places it in Abercynon Wales, from the Workmens Hall, also dating it between 1905 and 1990.
Any help with these would be greatly appreciated.
Thanks!
