A very pretty light and dark green marbled celluloid Wyvern Perfect Pen from, I would think, the late 1940s or early 1950s. This pen is in excellent condition with some minor foxing to the gold plating on the pocket clip being the only damage I can find on it. The flat-ended hard rubber cap top button still has an excellent deep and rich black colour with no noticeable fading. The top button holds on the washer style pocket clip. The pocket clip itself tapers toward the ball-shaped terminal. There is a single narrow gold plated cap band. The barrel has a good crisp and deep imprint that is very easy to read. The filling lever has a flat end tab . The 14ct gold nib is semi-hooded and has a medium point.
I have fully serviced this pen. If fills easily and writes very smoothly with a good consistent ink flow. The nib writes with an excellent wet and consistent generous medium width line.
An uncommon English pen in very nice condition.
