This beautiful pistol is a ČZ vz. 27 and chambered in 7.65 mm Browning (aka. .32 ACP). I am not sure when this model was first manufactured but it was at least as early as 1939 (feel free to share any information you have on this gun in the comment below). This particular CZ 27 was made just after WWII in 1946. Thanks to RobertP for sharing these beautiful photos with us.
