此相机产于德国慕尼黑K.W.(Kamera-Werkstatten Guthe & Thorsch)相机公司。1915年，Kamera-Werkstatten Guthe & Thorsch 相机公司在德国德累斯顿成立，创始人是两位犹太人Paul Guthe和Benno Thorsch。1937年，因为面临希特勒对犹太人的迫害，这两位犹太人考虑到自身的安全不得不分别移民到瑞士和美国。在这样的情况下，Benno Thorsch建议一位生活在美国的德国人后裔Charles A. Noble来接管公司，并更名为 Kamera-Werkstaetten Charles A.Noble。
此台相机快门采用德国F. Deckel COMPUR。
