Parker's line of sac-less pens. The first was called the Golden Arrow, but because of a patent infringement on the name was quickly changed to vacuum-filler. The next year the name was changed to Vacumatic. The Vacumatic underwent many changes and styles before it was discontinued in 1947.

Many pen makers developed their own variaton of the succesful Parker Vacumatic. All of their systems, with various technical solutions, do create a vacuum by pushing a rod into the barrel which then sucks the ink into the barrel.

One of the last Eversharp models before the company was bought out by Parker. Also called the burp pen, the ventura was not a high quality pen and was not a commercial success.

Nib almost completely covered by a plastic "hood" - only the very tip of the pen is exposed. Sometimes called a shrouded nib."

One of several terms used to describe the discoloration of pen parts (caps and barrels), especially those made of celluloid, due mainly to the effects of ink and rubber. This discoloration is not only superficial but affects the entire material of the pen.

Hard rubber discolors in response to outside influences, including water and light, which induce part of the sulphur to appear on the outside of the pen, thus turning it from ebony black to olive green. This discoloration is only superficial and the original black color can usually be restored.

Made by placing a piece of brass or other cheaper base metal and placing it between 2 pieces of gold. The 3 pieces were then bonded together to make one piece of metal. It was then run through rollers until it was thinned down to the desired thickness. At this point it would be like plywood or veneered wood. The item was then punched out or cut from the sheet and the bare edge covered. Not the same as rolled gold.

a pen that is sterling with gold-plating overlays. Vermeil pens are scarce, usually of very high quality, and considerably more valuable than sterling or gold-filled models.

A nib type first introduced on Wahl Dorics and later on the Wahl Coronet line. The nib has a slide on top that adjusts degree of tine spread and hence flexibility and line width. In contemporary nibs, it is found on the Pilot Justus, for example.
