Honest 66 Cartridge

In 1956, Platinum introduced the ink cartridge in Japan. To do so, the company marketed a modified version of the model Honest, an aerometric filler, under the name Honest 60, and the cartridge was labeled as Honest Cartridge. Many a pen brand adopted it for its pens and thus it became a standard. That was the case, for instance, of Mitaka and of Nobel’s, the later being another brand worth to write about.


The picture shows the initial Honest 60 cartridge, on top, and the current Platinum cartridge, on bottom. Note the differences in the area where the cartridges attached to the section.

That initial cartridge immediately went through some minor changes in the opening. By 1960, a further evolution of the Platinum pen, now called Honest 66, provided a larger and longer barrel where a bigger cartridge could fit. That was the Honest 66 cartridge. Unfortunately, this was short lived, and only the smaller version is available today.


Both cartridge/converter Platinum Honest pens. The Honest 66 (1960) on top, and the Honest 60 (1956) on bottom. The nipple of the former is well inside the section, thus allowing more room for the longer cartridge.


Both cartridges and the current converter. This has a capacity of 0.6 ml (0.53 ml according to the Platinum catalog).

The Honest 66 cartridge had a capacity of 1.7 ml, while the regular Platinum cartridge only holds 1.2 ml.

Mitaka

Not much information is available about the Japanese pen Mitaka. A review on an eyedropper from the 1930s, by fellow blog author Jule Okami seems to be the basic reference. Therefore, this pen, even if apparently unremarkable and boring looking, has some interest.

The whole contents of the box--that includes the service Platinum cartridge.

The Platinum Honest 60 pen, already reported on these Chronicles, was the first Japanese pen in using ink cartridges and converters. As a result, these cartridges were the first available in the Japanese market and several companies used them as the standard. Such was the case of Mitaka. This boxed set included a service cartridge branded as Platinum Honest 60 with blue black ink.


Other than that, this pen is made of black plastic, with cap and nib being gold plated. The very rigid steel point is engraved with the company name

This Mitaka pen is quite similar to the cheapest of the Pilot Super series—the Super 50 with steel nib. However, this pen is an aerometric filler. Both cost the same—JPY 500.

On both pictures, on top, the Pilot Super 50. On bottom, the Mitaka.

These are the dimensions of the Mitaka pen:

Diameter: 11 mm.

Length capped: 135 mm.

Length open: 120 mm.

Length posted: 155 mm.
Weight (dry): 10.5 g.


Mitaka is also the name of a city in the prefecture of Tokyo. However, the company was based in the ward of Itabashi.

My thanks to Mr. Alberto Linares.
