Having written about trench pens recently I am glad to be able to show this splendid example, the Swan Military. The ink pellets are stored in the base of the barrel but unlike other examples the blind cap does not need to be removed, just slid out to allow access to the pellets.
The pen is in what appears to be in used condition. The nib is flexible and, uncommonly, is marked “Toronto”. Swan nibs issued from that city are unusual but not unknown.
As I said previously trench pens are truly rare. Some were doubtless lost or destroyed in action but I think the conclusion is inescapable that they did not sell well. The pellets did, of course, but they could be applied equally well to any pen of the time.
There is much interest in trench pens though and between that and the shortage of supply together with its fine condition this is a very valuable pen.
Many thanks to Rob Parsons for pictures and information.
