The double trigger and 7mm makes me think it was a sporting rifle, especially if made after the war. Otherwise it could have been a special contract, CZ did make rifles for other countries. If it says BRNO, then it was made there. You do not mention if it was sporter or if it is a military rifle Also it could have been made for Spain, they seemed fond of the 7mm loading. Need pictures markings on receiver and the general layout of the rifle. Crest could have also been a special gun made for nobility. Need more info on the rifle.
