I have one of those "POA Small Packs", the Entrenching Tool, and the Water Bottle. But, I think they are all WW2 period. I seem to recall the pack I have has a 1942 date with the Broad Arrow War Ministry proof mark. The hand pick that I have is also dated 1942 with the arrow marking. I have several canteens, one has a 1942 dated strap. Sometimes I see the canteens with blue, or green enamel. Some British Canvas is light khaki colored, and some is a gray/blue color? I don't know why? Is that a difference between British and Canadian, or Australian, etc? I have some WW2 era gas masks, belts, backpacks, side bags, canteens, a canvas holster, ammo pouches, etc. I mostly know about American issue equipment.
