Sailor's Shut-Off

The topic of the shut-off valve in Japanese pens has already been covered on these Chronicles (::1::, ::2::). This mechanism has been used for about 100 years in Japanese pens (and in some pretenders) and is known as the “Japanese eyedropper”, even though there exists eyedropper pens in Japan without this system.

Needless to say, there are many examples of this system and some have been reviewed in here. However, few of them are as illustrative as today’s pen.

This is a demonstrator version of a Sailor eyedropper. It was probably made in the early 1950s. The engraving on the barrel, reading "Sailor / fountain pens", is the same as the one seen on a bulb-filler Sailor from 1952. The nib is made of steel and does not show any JIS mark.

The incription on the nib reads as follows: "Super Point / Sailor Logo / Non Corrosion / Pen / -4-".

An interesting feature is this pen is the metallic rod operating the shut-off valve from the tail. Usual concerns about the corrosive effects of ink on metallic part might induce to think that this pen was not for sale and was intended solely as a marketing tool for Sailor’s salesmen. The pen on display does not seem to have ever been inked.

The actual shut-off mechanism, controlled by the rod attached to the tail. In this case, the rod is made of stainless steel.

These are its dimensions:
Length closed: 131 mm
Length open: 118 mm
Length posted: 162 mm
Diameter: 12 mm
Weight (dry): 17.4 g

My thanks to Mr. Sugimoto.
