Empire Oversize Fountain Pen with Parker Duofold Nib.

Description

This is an oversize fountain pen from the 1920's in striated green.
Research info is sketchy, but all indications are this was a maker in the USA that was in business
for a only for a short while, then was done in by the "Great Depression" of the 1930's.
This does not have the original nib or feed. A Parker Duofold senior, 18k gold nib has been substituted.
With a new ink sac installed, the point is of a smooth broad width. (Makes a distinctive signature).
Dimensions are 5, 3/8" X 5/8" (135mm X 15mm)
Condition:
There are no cracks, deep scratches, bite marks or monograms.
Most of the gold tone has worn off the steel clip.
The nib iridium is intact: however, a small crack from the lower part of the vent hole is observed (a common flaw with Duofold nibs apparently).
With a new vinyl ink sac installed, the pen takes up a relative large volume of ink.
The cap threads are intact and the cap tightens down firmly.
