Hiya, this item was introduced in 1944.
Popular and very practical. The bag fastens up with a rope and a press stud flap.
This is the first pattern. It was later improved by widening the opening making it easier to pack/unpack. I will show the second pattern in the next post.
This one forms part of named group of items in my collection to Private M Heatley, W/161123.
Maker marked and dated 1944.
