Translations:Carter/8/en

Anyway the Carter pens were of excellent quality (with nothing to envy to the most famous ones done by Waterman, Sheaffer and Parker). The De Witt-La France owned also some significant patents, one for a very functional and easy to produce spring clip, then called Rocker Spring Clip, (nº US-1350412), another one for a tethered lever filler system (nº US-1209978), that allowed to limit vertically the travel of the lever, and another one for an efficient feeder (nº US-1340277), all these features can be found on Carter pens.
