Parker 75s for sale.

The Parker 75 fountain pen is a remarkable pen.  In 1964 it was offered at $25, a staggering price tag for a pen produced for the 'mass market'.  On paper it looked doomed, it was nothing like the Parker 51 or Parker Duofold, the most successful Parker pens so far, and it was a cartridge/converter filler.  The ballpoint pen was ravaging the fountain pen industry, and the 75 was outrageously expensive. 

Nevertheless, Kenneth Parker backed his own judgement, and that of his chief designer, Don Doman, and the pen went on to sell over ten million units.  It's a fabulous pen!
