Conway Stewart Nibs

Doug Wilson of Melbourne, Australia contacted me to see if any of you could help with identifying these mystery Conway Stewart nibs.
He says, “The set of nibs is said to have belonged to a late salesman employed by Conway Stewart. The outside of the nib box has no ID. The Conway Stewart logo inside the lid is the main clue that the box originates from the latter half of the 1930s. The fact that most of the nibs have heart-shaped breather holes (as opposed to the round ones that were introduced in the late 40s and 50s) supports this dating.
Most of the nibs are straight and either fine or medium but a couple are broad, two are oblique and one is “turned up” at the tip for particularly smooth writing. On the bottom row there are some really large, rare items – look at No. 26 on the bottom right, for example. There is information in the public domain which enables one to assign most of the nib numbers to specific pen models but there are others where, intriguingly, I have not been able to do this. The mystery numbers are:
Top row:       Nib No. 2V
Centre row:  Nib nos. ISM, 15, 11 and 1M
Bottom row: Nib nos. 27 and 8A
If any readers can throw light on these, it would be greatly appreciated. After years of collecting Conway Stewart pen and pencil sets, it is only recently that I have begun to understand the depth of information that can be imparted by nibs. It is like a dialect within the overall pen language!”

  1. Not my first time looking at these! However, I have just noticed that the nib labelled as 8A might not be correct. I can’t see any number on the large nib in that position, and the price is only 47/- which, by comparison with the others, seems to be much too low for such a large nib? It would be interesting to weigh the 8A nib in comparison with the nearby 6 nib, which is also priced at 47/-, this would give you some idea of likely relative values based on the gold content. My guess would be that the actual nib belongs to a 770 pen, for which Jonathan’s list indicates a CS ‘no number’ nib would be correct.

    1. As always, Andy, you drill down to the detail and I am most grateful for that. I have ordered a jeweller’s scale and will check a few of the nibs out.

  2. Andy’s post triggered me to wade through Jonathan Donahaye’s pen listing (again) and there I found one answer – nib No. 11 was fitted to the Pixie 358 pen launched around 1933. One down, six to go…
