These are original greek army pattern small packs, which are somewhat similar to their WW2 British counter parts.
Each pack comes with a shoulder strap and still have all the appropriate brass/metal work in place and in good condition considering their age and use. Unlike the british packs these have an extra webbing flap (this could be removed with relative ease) on the top cover that unfolds and can be used to secure a helmet to the front of the pack. These packs do not feature the internal dividers common in British Packs of the same era.
Measurements: 12 x 20 x 30 cm. Divided into two compartments. Removeable shoulder strap. Attachment points for utility straps on the sides and top. A strap flap for carrying your helmet, can be rolled up when not needed.
