given as a corporate gift in the late 1970's 

From the estate of a Holden service manager, with his name on box.

Still in its original box with end tab marked R, probably for Red, so probably other colours made.

Pen is full of blue ink but hardly writes - needs some coaxing to work again.

A well designed quality pen, folding out or away smoothly, or holding firmly in place using a spring steel closure.
