One thing the Wiki is not really that great on is historical dates and model/tool evolutions
It's something that we really need to try and improve.
Done a bit more work on this now and the following pages have all been updated with some historical information:
Classic, 58mm main, Princess, Pocket Pal, Climber, Camper, Spartan, Huntsman, Officer's Knife
Typically the history and identifiers sections have been updated and maybe the main top panel
Please check them out and let me know if they are OK and
if there is anything to add ......
