Product Description
Type Vintage fountain pen.
Product Name Parker Duofold Geometric also called "Toothbrush". These were all button fillers. This is the non-patterned version, less common than the ones with the toothbrush design.
Manufacturer and Year Parker, made in USA -- 1940 (The barrel date code is a clear 0 with three dots which matches the production years of this model).
Length 4-3/4", this pen came in two sizes: slender and standard. It doesn't seem unusually thin for the length so we're calling it the standard size.
Filling System Button filler. We restored it with a new sac and its working very well. The button does make a clicking sound when pushed though.
Color Solid black with a visiometer (partially clear section) to make the pen look like a vacuum filler when it isn't. It has a black cap jewel and a somewhat wide cap band with an etched line border.
Nib FINE gold Parker Pen USA nib is smooth with nice tipping material and a slight springiness. The feed is marked A which identifies it as a non-standard feed.
Condition Very nice condition. The pen has several blemishes but most of them aren't too noticeable. The clip and tassie are brassed and the cap band is scratched or dented. It looks more like tool marks than anything else. There are additional tool marks on the blind cap and a little melted spot on the cap. There are a few other marks on the barrel. The imprint is legible. No cracks, chips, or additional dents or scratches. The pen is fully restored and working well.
