Hello Gus,
I believe this tool kit is complete. It is not uncommon for the pouch to have extra pockets. Some years had a black plastic fuse puller also.
Many of the tools in the kit are the same in sedan tool kits of the era. The hard items to find are the special W113 tool pouch, the long handle pliers, and the fuse puller.
An additional "optional" lubrication service tool kit could be ordered which had the special grease gun for the door hinges, some other wrenches and the very desirable chrome "Mercedes-Benz" engraved tire pressure guage.
