Conway Stewart Dinkie 550

Regular price £70.00

Tax included.

The Conway Stewart Dinkie fountain pen was made, in a bewildering variety of styles and finishes, from the early 1920s up until 1972.  This pen, the 'Dinkie 550' is a 1950s version.

The colour is described as 'marbled green/brown flecks and veins' by Jonathan Donahaye in his seminal Conway Stewart classification. I think it describes it pretty well.

The pen has been fully restored and is now in near mint condition.  A new ink sac was fitted and the pen was thoroughly cleaned, checked, and tested.  A fuller description of the process is given below for anyone who is interested.

The Dinkie is a small pen and most users find it much more comfortable to write with the cap 'posted' on the end of the barrel.  The pen fills well and the 14Ct. Gold nib writes with a medium line and a pleasing amount of flex.  The line variation would allow someone with a decent 'hand' to produce impressive results.

The box is a little scruffy inside but is sound and of good quality.  It is marked 'Conway Stewart' on the lining and, judging from its size, it is clearly the original 1950s box.  Dinkies were usually sold as pen/pencil sets, this box probably housed a matching Conway Stewart No. 25 pencil, sadly missing now.

Notes on restoration:

The nib was not removed from the section as it was well aligned and the feed channels were clear, no need to disturb it without good reason. 

The cap was dismantled and the clip re-tensioned, this also allowed 'waterless' cleaning of the inside of the cap.  When the old ink sac was removed it was clear that this was the original sac meaning that this was the first restoration in sixty odd years.


It is common for modern restorers of fountain pens to replace the section so that the nib lines up with the filling lever.  When the pen was made these were sometimes known as 'side lever fillers' so I oriented the barrel and section accordingly.  I didn't shellac the section in place so it could be turned through 90 degrees to line it up if preferred.

The barrel and cap are made from casein, a milk protein which does not get on well with water.  Contact with water for a prolonged time can cause serious deformation at worst and, more often a 'crazing' of the surface if exposed to moisture.  This pen showed no crazing or other effects so all that was required was a clean and light polish.  No abrasives were used.
