This info helped me understand why my 452 is called a ZKM BRNO, and others are named the CZ. Thought it may be of interest to some you CZ owners out there. The dates aren't set in stone, but gives us a general reference.
In 1945, Czechoslovakian weapons Designer, Josef Koucky, introduced his version of the .22 caliber Malorazka, (meaning rifle), to an Arms Manufacturer named Zbrojovka Brno. Together they introduced to the world a highly prized .22 caliber rifle, and named it the “ZKM 451", after their own names, i.e. ~ (Z)brojovka; (K)oucky; (M)alorazka; 451, The designated 3 number identification, (45) indicating the year production began, 1945, and (1), identifying it as the 1st version.
Following in1964, Mr. Brno introduced another version called the “ZKM 452" which had a few modifications, mainly noticeable were the new ‘Tangent Sights’ adjustable out to 200 meters.
Along about 1982, another modernization of the sights and stocks produced the sought after ZKM 452 Model 2-E, which later began to trickle into the United States through Action Arms Ltd..
Sometime after 1995, and prior to 2004, several variations, a new ‘trigger mechanism”, and capped threaded barrel end, birthed the CZ 452-2E ZKM.
And as of 2004, two more versions have emerged, the CZ 453, with a heavy varmint barrel, and the new ‘Single Set Trigger’ design, and the CZ 513 Farmer, which is a basic version of the CZ 452-2E ZKM.
