The Charles Daly .30-06 double rifle you have is marked with "KBI Harrisburg, PA," indicating it was imported by KBI, a company known for distributing firearms in the U.S. The "Superior Grade" designation suggests a higher quality version of the rifle. The mention of "Bresciani" signifies that it was made by the Italian gunsmith, which is common for Charles Daly Firearms. For a more precise identification and valuation, consulting a firearms expert or appraiser familiar with Italian double rifles would be beneficial.
