Description C. Howard Hunt No. 508 Gold Plated Steel Pen Nib, ca 1930's. Imprinted, "Iridium Tipped U.S.A". Looks to be a fine point. Originally intended as replacements for fountain pen nibs, these could also be used as dip pen nibs. Approximately tapers down to 6mm in width at base, and 30mm long. Please note, vintage nibs do not size like modern nibs, and we cannot guarantee how well these will fit with other feed and section combinations. Excellent for practicing nib smoothing and grinding skills. We offer Free Shipping on all orders over $59 for US customers, and for orders over $250 for our Canadian customers.
