I have just acquired a Arctic Rucksack as used in the Falklands. This rucksack is in great condition with all straps etc but no frame. Any ideas where I can get an army H frame from or will a civvy one fit. Although it does feel comfy without the frame I dont know what it will feel like with some weight in it. I have a framed para bergen and it is good but the arctic one feels more comfy for my stocky build.
