Pen Model: Waterman's Junior
The 1940s were far from Waterman’s best years, in fact they were the endgame for the American company. Quality diminished as cash grew thin, and competition with Parker and Sheaffer was no longer possible. However, continuing Waterman’s long tradition of producing excellent nibs, these last models were good examples.
The one seen most often, and the one not given a military name, was the Junior. To my knowledge, there wasn’t a corresponding Senior, but this is actually a smaller pen, 4 3/4″ long, of black plastic and steel trim. Good pens, not great pens, but worth owning and using.
