Yes it is interesting. As a young guy I was really keen to see what the other carried. Australian army gear of the 60s and 70s was so minimal and we bought a lot of our gear or sewed it ourselves. A Kabar was a big deal. To put it all into context do a seach on google on the lrrp sites which influenced their patrolling doctrine of that era in the same way as now the British influence the New Zealand SAS and the US Special Foces and SEALS influence SASR. SASR are situated at Swanbourne Western Australia and if you look at companies such as Kitbag in WA you can see the material commercially available to the troopers there.
I am interested in the development of the personal combat survival kits much of which has a lot to do with the small bug out bag concept
I will dig into my storage and get my notebooks and post the rest of the lists. I collected lists of kits pre the internet so it might be good to pot them. Their contents are not exotic though.
