The scope appears to be a ww2 German sniper scope which the "cad" designation would indicate Kahles manufacture I believe if my memory serves me right. The manufacturer was coded to deceive the allies. They were usually 4 or 6 power magification. The mount appears to be similar to a Griffin and Howe type side rail mount which is derived from the ww2 German short and long side rail mount. Very nice rifle and the stock looks like it has very nice figure.
