This is a Sheaffer Imperial fountain pen with a 14K gold nib. The nib is marked "Sheaffer", not "Sheaffer'S", so it is not an early Imperial. I would guess it dates from the 1980s or '90s. The nib does not indicate the width; I suspect it is a Fine, but it could be a Medium.

The pen is overall in quite good condition. The nib shows some signs of regular use, but it is not scratched or bent. The surface of the barrel and the cap shows faint signs of handling, as does the gold trim, but no more than is inevitable in a 30-year old pen.

A squeeze-style converter is included.
