From this version, the model went to the third generation. Major specification changes were made in June 1931 (Pelikan Schreibgeräte). The most remarkable change was the designation of the pen (the official site). In 1931, the product range was expanded further⁽¹⁾. As a consequence, model names became necessary.

​

• "Pelikan fountain pen" with a sleeve in traditional green, black became the model 100. New sleeve colors (grey, red, blue, yellow) was also added (Fig.9).

• The Pelikan Gold was now called the model 111⁽¹⁾.

• The new model with white gold filled cap and sleeve was introduced (the model 110).

• The model 112 with cap and sleeve in solid 14 carat gold was officially introduced⁽¹⁾.

• The model T111 (Toledo) was introduced (Pelikan Schreibgeräte).

 

In line with the change of name, major constructional and material changes were made. Now, having the conical cap, the pen became slightly streamlined to the taste of the time (Pelikan Schreibgeräte)(Fig.2). As a result of the inclined cap and grip end (Fig.6), they were faced obtusely and thus called “diagonal seal (Fig.4)." As the diagonal seal was more effective, the lateral seal became unnecessary (Pelikan Schreibgeräte). In the third generation, the lateral seal was at first preserved, but later abandoned. Though shortened, the nib socket held the nib and the feed tightly and fitted securely into the grip section.

 

As for materials, “They went to celluloid and hard rubber construction” as “Bakelite is heavy and brittle and like hard rubber does not take color well (A History of Pelikan).” The grip section was screwed into the barrel. The joint lay in front of the threads for the cap (Pelikan’s Perch). The internal thread of the celluloid barrel was reinforced with a brass ring⁽²⁾. Also, the brass ring, fitting the sleeve, helped to hold it on the barrel (Pelikan catalog No.60 (1934)). The original color of the barrel was described as "grün" (green) in Pelikan catalog No.60 (1934)(please see Fig.9)⁽³⁾.

 

Note;⁽¹⁾In 1930, Günter Wagner had already introduced "Pelikan Gold" "an unofficial model later known as the model 112 (Pelikan Schreibgeräte).

⁽²⁾The earliest celluloid barrels had no such a brass ring (Fig.7).

⁽³⁾Today, most green celluloid is found to be denatured to amber color or opaque black due to ink stains, ultraviolet light, and other factors.
