GMichalski,
Safonov made 18+4 claims during the war, of which 1+2 were counted as "probable" (yes, in The North Fleet Aviation did exist such claim category, although it contradicted the common VVS rules).
You may find the full list here:

That list was compiled using only an operational documents and therefore must be considered as the most accurate we have to date. It was recently published in excellent book "The Soviet aces. The victories of Stalin's Falcons" by Mikhail Bykov.
