I never completed it, but always tried to add one or two over time. I always bought with an eye to quality and the best I could find at stamp shows and dealers. All are original gum, MINT, Never Hinged, and have been stored in my collection binders in Scott mounts, and in a smoke-free environment. Best of luck and thanks for looking. C7, 8, 9,10 (1926-27).
C32, C33, C34, C35, C36, C37, C38 & C39 (1946-49). C40, C41, C42, C43, C44 & C45 (1949).
