Introduction:
In 1968, Pilot gave another turn to the idea of a capless pen by creating the Capless without any pushing (or pulling) mechanism. The 1968 model is probably the most original among all Capless models ever made by Pilot or by any other maker.
C-250SS, first model, initially released in May of 1968.
The second model had a black sliding button in the clip, otherwise fixed to the pen body. It was released some months later than the initial version, probably already in 1969.
Features:
Pilot C-250SS. 1968.
Dimensions:
The black piece on the back can be uncrewed to access the nib unit.
Nib unit:
Type V. In 14 K gold. This is the first Capless model to use single spare cartridges and converters CON-20 and CON-50.
The type V nib unit. The metal sheath on the back hides the single spare ink cartridge. To use a converter, either CON-20 or CON-50, the sheath has to be removed.
Detail of the nib unit. The step under the nib secures the position of the nib released to write.
Additional information:
Two variations existed on this model. The first one, from May 1968, had the whole clip sliding to open the way to the nib. The second model, released some months later, has a black plastic button on the clip. Pressing it operates the mechanism to release the nib. The clip is fixed to the pen body.
As is the case of most Pilot pens of the time, both the nib unit and the body are dated.
