Okay, clearly this is stumping a few people. Further clues - most of you missed the 'semple' clue I threw in earlier. Colonel the Master of Semple led the British naval mission to Japan in 1921 and examples of this aircraft were sent along with the mission. it was carrier based, but was not a fighter, nor was it a torpedo plane, so the Cuckoo and Swift - not two seaters at any rate can be discounted. Like I also pointed out, the US Navy operated them, too. Keep guessing - it's an obscure lesser known type, so you're gonna have to get out your books and do a little research...
