Pelikan Primapenna

The first Primapenna were made by Merz & Krell on behalf of Pelikan Milan. The first generation of Primapenna does not have any profiling at the grip section and the gold-plated nib is covered up to the triangular hole. A metal ring is used between the grip section and the barrel to secure the cap. The ring on the cap opening is tapered, it is embossed with 'Pelikan Günter Wagner'. The bar clip comes together narrowly and is embossed with 'Primapenna'. The end of the cap made of the same color plastic bears the Pelikan logo.
There will be more color options than the ones listed here.

Weight	Total Length	Barrel Length	Cap Length	Diameter	Ink Capacity
0.32 oz	5.28 in	4.29 in	2.56 in	0.39 in	2 x 0.8 ml (cartridge)
9.0 g	134 mm	109 mm	65 mm	10 mm

At this model variant, two different packages are known to me and the fountain pens has a tiny difference, too.
The first package shows a feature that was otherwise not so common at Pelikan. The fountain pen was equipped with two cartridges. Thus, the writing cartridge is not activated immediately and can dry out, a locking ring between the barrel and grip section was screwed. This must first be removed, according to package instructions, before the fountain pen can be taken into use (see picture). This method is well known to me from other manufacturers. But Pelikan used usually a different method: the writing cartridge has been replaced with a dummy (without ink cartridge, and without the rear cover of the cartridge). Only the replacement cartridge is filled with ink. Further, in this package was an instruction manual for the 'Pelikano'. The fountain pen itself shows the transition from the grip section to the barrel, which is to enter the closed cap the maintenance, a slightly roughened surface.
The other fountain pen packaging don't show this statement to remove a retaining ring (see picture). The fountain pen surface to grip the cap has slight ridges (see picture).
Probably there are more color options than listed.

The change of this serie Primapenna can be ssen specially on the clip, the clip is plugged in at the top of the cap.

These models of the Primapenna come from the production of the company Mutschler in Heidelberg. The moulds are similar to the pens Mutschler made for Laurin/Pelikan, but with the Primapenna logo on the clip. It is unclear whether these models were sold on a regular basis or only as model samples.

Weight	Total Length	Barrel Length	Cap Length	Diameter	Ink Capacity
0.27 oz	5.31 in	4.49 in	2.30 in	0.39 in	2 x 0.8 ml (cartridge)
7.6 g	135 mm	114 mm	58.5 mm	10 mm

The design of this Primapenna has been substantially revised and will have been manufactured by Mutschler. Cap and barrel have a cylindrical shape. The cap and barrel ends are closed by a plastic plate of the same colour. The metal clip shows the lettering 'Primapenna' and the Pelikan logo. The nib no longer has a triangular hole and the simple stainless steel nib has no iridium writing point.
It is also interesting here that new fountain pens are delivered with a safety ring to prevent the inserted ink cartridges from already being opened (see also Primapenna 1970s).

Weight	Total Length	Barrel Length	Cap Length	Diameter	Ink Capacity
0.35 oz	5.41 in	4.25 in	2.38 in	0.41 in	2 x 0.8 ml (cartridge)
9.9 g	137.5 mm	108 mm	60.5 mm	10.5 mm

Also this series comes from the production of the company Mutschler Schreibgeräte AG. The bad economic situation and the increasing price pressure caused the manufacturer great difficulties during this time. Thus it is not certain whether these models were offered on the market for a short time or whether they are only samples.

Weight	Total Length	Barrel Length	Cap Length	Diameter	Ink Capacity

The Primapenna is now completely redesigned. The new Primapenna from 2013 is made by Herlitz, a company belongs to the Pelikan group. The pen is identical to the model 'SmileyWorld' from Herlitz. It consists of injection molded parts in two colors each. Barrel sleeve and cap sleeve are the same color, barrel end, grip section, cap end and clip are made in another color. The colors are strong and sometimes garish. They should meet the tastes of youth, for these fillers are determined. The nib with iridium point is exposed and very similar to a classical fountain pen. The cap margin is printed with Pelikan and the logo. No evidence suggests more attention to the model Primapenna.
