This appears to be an early post WWII Japanese binocular despite its German sounding name.   No J- markings are visible.  Also, it is not really "Extra Wide Angle" as marked, but has just a moderate field of view.  It is fairly well made, with a one piece B&L style body, individual focus eyepieces, and shielded prisms (though they are low index).  The coated optics have good image quality, with just a slight amount of prism leakage.
