Two spare refillable glass ink cartridges for Waterman cartridge filler pens from the mid-1930s, made for the French market, both 65mm long. One is clear of ink and the other is intact, the ink dried up but with the stopper still in place. Both in excellent unchipped condition. I bought these as spares to use with a rather nice silver Waterman cartridge filler which I no longer have.

The cartridges can be refilled using an eye-dropper or syringe or the plastic pipettes sometimes supplied with gardening root-killer (powerful stuff!)

The idea of a cartridge pen is nothing new (Eagle was making glass cartridge pens as early as 1890). Nonetheless, the history of the modern cartridge fountain pen really begins in 1936, when JiF Waterman – Waterman's largely autonomous French agency – introduced a line of American-made pens modified to take glass cartridges. The "Made In USA" imprints suggest that these modified pens were, at least initially, specially made in the US for the European market.
These US-marked pens were based upon the 92/32 and 3V series. Before long, however, more distinctively French models were introduced, including some fully covered in silver or gold. The bottom pen in the image above does not even bear the Waterman name, but only that of JiF, along with the imprint, "Fabrication Française" – yet the 18K nib is still US-made.
Production of these pens appears to have been interrupted by the Second World War. The "Standard" (middle, above) is a postwar example, but by 1953 Waterman had introduced the C/F, the fountain pen that inaugurated the era of plastic ink cartridges and relegated the glass cartridge to obsolescence.
Waterman glass cartridges are sturdy and can be refilled and reused indefinitely. They were originally sealed with a cork stopper which was pushed into the cartridge by the tail of the feed. The one part that may need replacement is the cup-shaped seal in the back of the section, as it is made of rubber which is prone to hardening with age. The glass cartridges were made in three sizes: long (65mm), short (52mm), and Super (80mm), the last introduced only towards the end of glass-cartridge pen production.
