I might have a rifle like the one Mickey described. It also was made in '49 with double set triggers chambered in 7x57, and it drives tacks. It is factory milled for rings and the safety is on the left side. It has the CZ emblem on the top at the front of the reciever but has the factory's name(?) on the outer left hand side. If I could only have one gun, this would be it.
