This is the legendary Norwegian army "Telemark" Pack. I say legendary, because this pack was dragged along by Kirk Douglas himself in the 1965 movie "The heroes of Telemark":
Classics never die. This Norwegian pack is a tried and true design used for decades in the Norwegian Military. The sturdy metal tubular frame ensures this pack will outlast many modern packs. Featuring leather shoulder straps, rain/dust flap with leather strap closure, drawstring close main area, 2 large side pockets, and bedroll straps. Measures approximately 18’’ x 6’’ x 18’’. Weighs approximately 4lbs.
