| 1956, Academician Alexey Krylov, 40k gray, brown and black, perforation L12 1/2 instead of comb 12 1/2x12, top left corner sheet margin block of four, unused, expertly regummed, VF appearance of this very rare perforation variety especially in positional multiple. We are of the opinion that original gum was removed because of its heterogeneity; microscopic examination showed no evidences of CTO on that block . |
