A good day at the flea market today!

Something I just noticed on the photo of all the tools you just posted is that the pick axe and handle are not the typical Canadian/British military issue with the metal re-enforcing on the handle and the shallower head where the handle goes through. The pick axe and handle shown are more the American style, which is also the style commonly found today here in North America.

Also interesting is that it appears that there is a chain coming off the jacking block. It would save the driver from having to crawl under the vehicle to retrieve the block after changing the tire as well as help positioning the jack and block before raising.

I suspect the little clip that holds the tools together was a fairly standard item with Gray tools. below is a shot of a set of double box offset wrenches using the same clip.
