Lovely rare blue lizard skin De La Rue lever fill fountain pen from early 1900's. New sac fitted. The pen is in generally good condition, though the cap has some minor heat damage (local shrinking above the gold bands) and a minor crack (see last image). It writes with an original 14k gold knib. There is evidence of a number 622? On the edge of the top black end. A great pen for the discerning collector.
