Parker Royal Challengers are handsome vintage pens that offered a slightly less expensive option for pen users who couldn't afford the flagship Vacumatics. This pen is nearly perfect, except for its nickel-plated trim, which is heavily worn. We restored this pen with a new ink sac. It is a button-filler like the older Parker Duofolds. Its ink viewing window is ambered. You will write a nice fine line with its 14k gold nib. Click the headline for close-ups. It has a clean imprint that states it is from the first quarter of 1940. 12.2cm capped.
