RAF WORLD WAR TWO CANVAS KIT BAG

RAF canvas kit bag, early 1940's.
Kit bag is showing some wear, mainly a little fraying to the lanyard holes along the top, three of the metal rings are missing from th bag.
The bottom of the bag shows some blackening to the canvas, I don't think it's mould, maybe just age?
There is also a small rip at the bottom left corner.
All in all, I would say fair to good condition.
A very nice genuine item.
