Physical description

Single person water filter bag used by World War 2 service personnel to obtain clear water when in the field. This filter type is known as a "Millbank Filter".
The filter is in the form of a light green canvas bag shaped like a sock and is designed to collect and filter particles and parasites from groundwater, etc. The canvas is of a fine weave which allows the water to filter slowly from inside the bag. The top of the filter bag has brass eyelets set on opposite sides for hanging from a tree or other point during water filtering. On one side of the bag has been stamped in permanent black ink 'CAT No A.F.0005' and 'M&Co.(N) BROAD ARROW 1945'. A cotton label has been sewn near the bag top with a printed six step instruction list for use of the filter bag. Below this is a line marked in permanent black marker to let the user know when to start collecting the water draining from the bag.
