WW2 Fleet Air Arm aircraft identification

I visit a veteran from the Arctic convoys. He has a few photos but cannot remember the type of aircraft in the attached photo.

(I see some of the crew are in shorts so maybe not in the Arctic this time)

That is very helpful and interesting. Thank you.
My friend could only remember the aircraft types as the Fairey Swordfish (obviously not correct for this photo) but he also said he was 813 Squadron, and HMS Campania was one of the carriers he operated on. This fits in nicely with information on Wiki.
