We think that this is the short-lived Imperial fountain pen made in Nassau, NY. The cap band is imprinted with the Imperial name, much like the very rare Parker Vacumatic pens with a "Vacumatic" engraved in the cap band. We think the trim might be plated-silver that is brassing. A good ink sac has been installed. We love the blue-and-grey design. It comes with an "Imperial" imprinted 14k gold nib. Click the headline for close-ups. You will see the bottom side of the nib is cracked in the photo. You will write a semi-flex line that grows from extra-fine to about 1mm wide. It is a big scratchy. 13.3cm capped.
