Red Hard Rubber (rhr)Parker Duofold Senior Big Red (5-1/2").
PARKER DUOFOLD
Typical Red Hard Rubber Parker Duofold Senior with Medium Imprint.
Click here to email for details.
Several of these pens have reconditioned (re-tipped) nibs, including reconditioned italic
and stub nibs.
Italic nibs give a calligraphic flair to your writing by making broad verical
strokes and narrower horizontal strokes.
Stub nibs are similar to italic nibs. They too make rather bold strokes with your pen.
Single band model (1926-27).
Double band model (1928).
Click here to email for details.
I usually have several proper reconditioned nibs on hand, including
a few italic nibs, that can be installed in any Duofold Senior.

crazed and discolored) I sell replacement rings as well as pairs of white border bands.
Here are the rings I currently have available. Rings are $40 each postpaid and the white border bands are $15/pair.
