For the blue Super Corsa, I read the day of week, week of year, year numbers as 4 4 3 1, evenly spaced and all struck at the same time. The 2 and 6 straddling the first 4 indicate the 26th frame of the day.
For the hangerless TdF, I read it as 5 4 9 1 and the 34th frame of that day.
So both would appear to be 1971 frames.
