Good eye Henry,
To be honest, I thought the Sea Venom was a two seater as well and you are right, that one doesn't look that big, nor does its nose look like a radome. However, the one pictured is N-202DM which is listed as a "DH112 Sea Venom" on the FAA Registry. How could the feds possibly get that wrong?
De Havilland apparently produced 816 single seat Venoms, 283 night fighters and 393 Sea Venoms. How many versions was the designation DH112 used for?
You are also correct about it being ex Swiss AF. Produced in 1955, serial number J1616.
I better go break out the recognition books.
Bonus shot anyway!:
