Julian is correct. There are 4 variants of "angle drive". Two ratios and two manufacturers.
There are also several Kmh speedometers.
One variation is a "dual scale" having both, but with the Kmh scale dominant.
The other two (at least) versions differ by the "digit spread".
(One has the scale marking in units of 30 (Km/h).
