Old VW tool box

In the beginning of 1950′s Hazet (West Germany) started making a round shaped toolbox that has perfectly cliped into the spare wheel of a VW Beetle. It was over in the end of 1960's. Of course it has worked very well in VW Beetle, Buggy, Rail Buggy, etc. My brother have one in very good condiction (my father heritage), but it is not for sale. They had said that with these tools a driver with some skill and mecanical knowledge would be able to fix the car. Really the germans overstated a lot, but these tools were quite useful. 
See the old sparkplug socket for VW boxer engine. It seems smart.
