Following up on a recent post about the Waterman Signagraph machines: what are those lock boxes about? The lock boxes that accompanied some of the machines were designed and used for storing the fountain pens and inks that were used in the signagraphs separately from the machine itself. The purpose of the boxes was simple – it was a security measure; by having the pens locked away from the machine itself, a corporation could more likely prevent unauthorized use of the machine.
