What are the stats, Frequency Response for ADC 25?

I recently had aquired a new in box ADC 25 Stereo Pickup System. It did not come with any paperwork. What are the stats for this cartridge, in particular frequency response at some point or points. Thanks, Gerald.
Dear G: I suppose that the 25 is very similar to the 26 because the removable sylus/cantilever characteristics are the same and can use it with either one.

Here you can read something n the 26:

Regards and enjoy the music,
