(haven't look at mine for a long time) From memory, the lambda counter has a 3 counter display (mechanical like the odometer at the dash binnacle).
The counter rotates 1 for every 300 miles of mileage. At 100 on the counter (30k miles covered - 100%), it clicks the internal switch closed to complete the circuit for the LAMBDA indicator at the dash binnacle, indicating it's time to check the lambda system and potentially change the oxygen sensor. You need to then reset to all ZEROS again, and then the counter starts winding up until it reads 100 again.
...From memory.
So in the case of this auction car, in theory, the lambda counter was still reading 001 for less than 600 miles covered. (I didn't look myself)
If the angle drives breaks though (at the wheel which is the most common break point) then it stops everything from turning. No speedo, no odometer, no lambda. So unless someone winds back the odometer and forgets the lambda counter, or the angle drive line breaks between the lambda counter and the binnacle connection, you'd expect the two to always marry up.
