External frame rucsac (Abbeyhill EH7)

If you want this, you are probably familiar with it. A mid-seventies Karrimor rucsack with an external frame. As well as being useful as a not especially comfortable or waterproof rucsack in its own right, it is also exceptionally useful for carrying awkward loads strapped to the frame, resting on the ledge of its L-shape. A musician with an awkward large case? Firewood collection, or perhaps a carry-in of materials for a bothy work party.
