The VS was one of Parker’s lesser lights from a justifiably confused period — a 1946-49 attempt to introduce a pen that looked like a 51 but with far less costly features. No one seems to know if VS stands for “Vacumatic Successor” or “Victory Successor”, since neither name makes complete sense. It is a hybrid: a successor to the Vacumatic, but a minor one in comparison to the 51. It carries the Vac’s open nib and Duofold’s straight clip. It is a button filler like the English Duofolds, probably using the same button and pressure bar. In summary, a 51-like body with numerous non-51 features. VS’s were made in limited quantities over only three years, and their relative scarcity has increased their desirability in recent years.
