Years ago, when I was trying to restock my CS, I found the guts of the toolkit had it's own part number. From memory, it included about 5 ring spanners, the 2 box spanners, 2 screwdrivers, the multigrips, the 'adjustable' spanner thing, and the long steel rod which fits in the box spanners. THey were all Heyco branded, of course. The Allen keys were the surprise omission, along with the feeler gauges. Try your dealer - you might be surprised what's available,
