Waterman's "Safety Pockets"

Browsing in old fountain pen catalogs, one often runs across items that just don't seem to turn up in real life.  The leather pen carriers sold by Waterman and others provide a good example: they appear regularly in Waterman catalogs from around the turn of the century up through the 'teens, listed as "Safety Pockets" or "Vest and Chatelaine Pockets", yet many advanced collectors have never seen actual surviving examples.

I've owned these two for quite a few years. Both are vest pocket versions, as opposed to the chatelaine versions which have an inverted V-shaped suspension system, allowing the pocket to hang from a woman's belt.
