CS270: Conway Stewart Dinkie No. 550.

Date: c1950s

Size: Capped - 4 1/4 inches, posted - 5 inches.

A very pretty little Dinkie made from a very attractive burgundy and gold end brown marbled casein.  Casein is a form of plastic made from milk proteins.   This pen is in excellent condition, the only damage being a tiny bit of plating wear to the pocket clip that you can see in the close-up cap photo below, but which is hardly noticeable without magnification.  The cap has a small conical gold plated top button that holds on the gold plated pocket clip that has the "CS" monogram within a diamond at the top and another diamond at the bottom.  There is a fairly narrow gold plated cap band below the pocket clip.  The barrel imprint is crisp and deep.  The cute little filling lever has the "CS" monogram imprinted in the circular end tab.  The nib is shiny and totally undamaged and is a medium point.  

I have fully serviced this pen.  The nib writes very smoothly with a very nice wet and medium width line.  The nib also has a little softness and will provide a little understated line width variation when used with normal writing pressure.
