Ceylon. Used. Interesting accumulation of thousands of stamps, from Queen Victoria to Queen Elizabeth II, all used. While the Queen Victoria is important for varieties and small town postmarks, similarly with Edward VII, it is the King George V pictorials of SG#368 to #378 and King George VI #386 – #397 for a study of the perforation varieties with considerable potential here. Modern goes up to Birds high values etc. Definitely for the specialist.
