Conway Stewart Churchill Hard Rubber pen

With reference to the posting by Quarterhorseman.
Please do not take any notice of the suggestions or opinions
in this article, disassembly of your pen will invalidate
your guarantee. The author is obviously unqualified and does
not know what he is talking about, and is most certainly not
a qualified engineer. It is obvious from the photograph
that this person has already damaged his nib by crudely
taking apart his pen, and heating the barrel with any kind
of flame is not recommended.
Any leakage problems experienced has been due to a defective
batch of sacs from the sac manufacturers, this has now been
cured. The theory that fatness of the sac is causing the
pen towrite 'wet' is a complete fallacy, and certainly not
based on any engineering principle.
