On box is written 760 km/h, is this mean that this is universal device? I am not sure that Stuka can reach that speed, even in dive!

The Ju 87 couldn't reach that speed, but the Ju 88 could (at least theoreticaly in a steep dive). But AFAIK there is a limiter in this device that this speed shall not be reached in a controlled dive. So, yes, this would be a universal device for planes like the Ju 87 and/ or the Ju 88.
