Special piston, developed by Montblanc in the 30ies. Here is a little instruction on how to fill a Montblanc Pistonfiller with the famous telescopic piston. These were used for the high end Masterpieces 13x and 14x as well as in some 234 1/2 pistonfillers. First thing to note, when starting to fill the pen - unscrewing the turning knob, at first, the knob turns loosely, without engaging the piston. Only after several turnings, you will find resistance, and the piston will start moving. Then, you must make sure, the piston head moves up completely, till it gently touches the section. Only then the piston will move back completely. Otherwise, the piston might stop halfway. The pictures show in detail how this system works. Thanks to Francis Goossens for this technical drawing.

When Wahl bought the Boston Pen Co. in 1917, to add pens to it's line of Eversharp pencils, the first pens produced were called Tempoint. This was basically Wahl's name for the exact pens produced by Boston. In the early '20s, Wahl focused on metal pens and the Tempoint name was dropped. Wahl's line of hard rubber pens became known as the Signature line.

The pen part under the nib that allows for flow of ink to the nib as air moves into the ink reservoir. Until recently, feeds were made of hard rubber. Today they are made from injection-molded plastic.

Same as ink feed, or feeder.

Any rubber or latex ink sac that is depressed by a variety of mechanisms to draw in and hold the ink supply.

Pill shaped piece of dry ink that was mixed with water inside or outside of a pen to make ink. Mostly associated with World War One soldiers who used them to make ink on the battlefield.

Desk pens usually consist of a desk set, with the base being the marble or other heavy material onto which a holder is fitted, and the pen itself called a desk pen. Desk pens typically have a distinctive taper shape and no cap. Some desk pens, however, were convertible to pocket pens by removing the taper, and adding a blind cap and a cap. Desk sets range from simple single pen models to double pen sets with elegant statues and lamps or clocks. Desk sets tend to be undervalued in the vintage market due to the size and weight of the base.

Sheaffer's name for the famous conical shaped nib introduced in 1942. Later used as the name for a pen model.

A clip with a clip ball shaped like a teardrop. Found with certain Monblanc pens from the 1930s and 1940s as well as on some Pelikan pens from the same era.

a late '20s Parker button-filler of blue and white plastic. The white was very prone to discoloration and True Blues are very hard to find in good color. They were made as pocket pens and ring-tops.

a pocket pen from Sheaffer in the mid '40s. Tuckaways came in many varieties and were made as either plunger-fillers or touchdown fillers. Most had a short clip, but some were made with no clip.

Pens that employed a rubber ink sac, but used a mechanism to twist the sac to expel air and create a vacuum rather than a pressure bar as with other rubber sac pens.
