Not belonging to an original toolkit, but a nice period correct* addition: an 15-17 bent ring spanner. Super handy if you need to replace that starter motor, it's about the only way to get the top bolt out with a full engine bay.
As with original ring spanners it has shiny chromed ends, and it uses the 'No' with a small line under the zero.
* it does say GERMANY, and not W-GERMANY, which has me wondering. Could it be post unification but made with older tooling that was modified to take out the "W-" part?
