New Delhi Specimen Rouletted Perforation Set of 8 stamps – each with a different colour combination. Odd faults as all in usual mint or unused condition. Specimen with these experimental Rouletted Perfs are practically unobtainable and to find a set of 8 is a once in a lifetime opportunity. Rarity.
