Return to Soyuz

Piston Filler

Maker: Soyuz.

The front end of this pen is quite similar to the first sort of Soyuz I was able to examine; a hooded pen with an oddly flexible point.  The main point of difference lies in the filler, as this variant on the Soyuz theme has a relatively standard screw-operated piston-filler concealed under its barrel.  This is a rig which is frequently called a \”captive converter\”, in as much as the piston doesn\’t actually contact the barrel.  The only functional drawback to this set-up is a rather reduced volume of ink available, although this pen doesn\’t suffer too much from that since this is not a true captive converter (in which a converter is in fact glued into what would otherwise be a cartridge pen).

Production Run:  Due to the filler, I\’m inclined to say newer than the accordion-filler, but I have no basis for that.

Cost When New:  No idea.

Size: Desk version; 16.2 cm long.

Point:  Steel?  \”Not gold\” is all I can really say with certainty.

Body: Plastic.

Filler: Piston, capacity approx. 1.3 ml.
