@ Nick4 - I put those San Marino images in the 111mm Rescue Gallery in the Wiki - I knew you would not mind!!
Couldn't give exact time frame for beginning of issue but the New Zealand Army was issuing soldiers to troops from 1973 on (a friend had one from basic back then) . From approx 2003 on, the Victorinox centurion is the issue knife (handed back as I left the army regrettably 🙁) Ive since got my hands on a replacement which ill get a pic of up when i remember. As far as i know, none of these had national flags etc or other markings.
