Go to the CZ USA website to see what they chamber for.
Made in Czechoslovakia, Brno is now in the Czech Republic.
some are, some are not. That is a make of rifle, not a model.
From my experience, BRNO rifles are very nice. They are no longer made under the name BRNO, but CZ, and although the manufacturing processes may have changed, the CZs are near identical to their BRNO ancestors. Try to get a BRNO model 2.
10-1000 USD depending on specifics
Assuming you mean a Brno 602, it will depend on the caliber that the rifle is made in. Brno 602 is a make and model, not caliber.
You will have to contact the factory.
You need to talk to a gunsmith.
15 million dollars
Used, yes, New retail, doubtful
Brno is famous for its history places.
Brno is in Czechoslovakia, Essen is a city in Germany. Two different countries. "fluss stahl" refers to "fluid steel" made by KRUPP Industries located in Essen, Germany. Since Krupp was one of the premier manufacturers of high quality steel products in Germany prior to (as well as after) WW2, there is a good chance that Brno used KRUPP steel to produce rifle barrels. Especially in the late 1930s.
