The Youngs Valvespout cans contained 303 rifle bore cleaner and rust preventative, not lubricating oil, but as they are refillable the contents could be changed. It's a pity Webley didn't use a similar can.
There are three different types of the canvas and leather pistol case, and at lease two of the post war Rexine case. I've had all the variations in my collection at various times, but unfortunately did not take any detailed photographs before I sold them.
