British W.W.II P37 Large Pack
The British WWII P37 Large Pack was an essential component of the Pattern 1937 Web Equipment system, which was heavily used by British and Commonwealth forces. This heavy canvas backpack was worn on the back during "Marching Order" and was intended for larger personal equipment items during relocations.
Key Characteristics and Construction
- Material: Made of extremely robust, water-resistant 100% heavy-duty cotton (webbing) with brass buckles and metal hardware.
- Dimensions and Capacity: A simple, spacious rectangular main compartment measuring approximately 30 cm wide x 25 cm high x 12 cm deep (roughly 15 to 20 liters in volume).
- Stamps and Markings: Original examples feature an ink stamp on the inside of the flap detailing the manufacturer's initials, the production year (e.g., 1940–1945), and the Broad Arrow (the arrow mark of the British War Department).
- Color: Standard issue was a light khaki/olive green shade. Soldiers often coated the pack with "Blanco" (a colored paste) to adapt the equipment to the terrain or unit requirements. Post-war variants were also produced in RAF grey.
Operational Use and Loadout
In the field, the equipment was split: the Small Pack (haversack) was carried on the hip for immediate combat essentials, while the Large Pack went on the back. Due to its bulk, soldiers often left the Large Pack behind in transport vehicles or the base camp before launching an attack.
The standard contents of the Large Pack included, among other things:
- The greatcoat, folded or rolled up on the inside
- Spare clothing (shirt, socks, and underwear)
- Rations and personal mess tins
- The Brodie helmet, which was often fastened to the outside with extra straps during movements
Carrying Method
- Marching Order (Backpack): The pack features two brass buckles on the back. The L-shaped P37 shoulder straps hook into these, run over the shoulders, and are attached to the ammunition pouches or the waist belt at the front.
