My Hilka set is over 50 years old, I haven't broken anything but lost the odd socket, which I replaced with Britool, Anybody need any Whitworth socets?:):)
52 years motoring, on motorcycles and cars, in that order, no accidents in the last 17 years. Only at fault accident 42 years ago, so I ticked top 10%.
