This is a 1932 Meteore (Pullman) #1 BF in Black Hard Rubber over a brass lining. Unsigned cap and barrel, other than “PATENT” on clip. Correct “D & D Paris 18 Cts 1” nib (Demley & Degan were the founders of La Plume d’Or, the French company which licensed the Pullman technology). This high quality, rare and famous pen, which opens and closes by pushing up & pulling down the barrel, which opens and closes the hinged crown on the non-removable cap. Few were made, fewer survived as folks broke them trying to unscrew the cap! Medium, extra-flexible nib. Near mint+. Shown open and closed.
