The only way to find out how old a Bretta automatic pistol with the serial number 605222 is to call the company. There is not a listing for Bretta's by serial numbers online.
Browning records of serial numbers on the 1910/1955 model are vague before 1966. They estmate that number 500,000 was made around 1965, and that 550,000 was the beginning of serial numbers made in 1966. Yours is probably 1965.
