Dassault Mystere II
edit: though it is no delta wing, and first flight in 1951. Mystere iv 1954, but cockpit a bit different.
Then theres the MD550 Mystere Delta, but the sources I found state first flight 25th June 1955, and I can't find any cockpit picture.
Edit2: Another source claims the mystere-delta first flight on 25th June 1954, so either is incorrect. But I cant find a picture of the cockpit so cant be 100% sure.
