Accordind to Shores and Cull, the opponants were the 22nd air flotilla , so it was definately zeros that the Hurricanes were engaging. Also at this time , March of 42, I don't think that the Ki43-IIs were deployed yet.
I"ve got a few of Terrence Kellys books, Hurricane vs Zero [Battle for Palambang] , Hurricane and Spitfire Pilots at War and Nine Lives of a Fighter Pilot. I've got Hurricane Over the Jungle on order. All very good books, well researched and quite insightful . Good companions to the Bloody Shambles series .
