There was also the Walther Rangefinder which was a Hakko derivative... 10-40x56, different to the custom shop in turrets and a different eyebell. Mildot and crosshair. There may be subtle dimension differences but it shares a lot in common with the CS. Does seem to differ between mildot and hair in terms of parallax direction and mag from the few examples I have. The crosshair is finer than the CS's i've looked through.
