4 otu Harvard codes and tracking some family history

[ryanbiddick]

Hi there I’m trying to locate what the codes would be on the Harvard my great uncle flew (Stephen Webster). From what I usderstand, most of the 4 otu aircraft started with the codes OD? But going by the picture it could possibly be O v,w,y,x??? All I know is he was at Ohakea 1943-44 4 otu and this is the image I have to go by

I also know he went on to fly p40m nz3115 at 4 otu where he was killed later on in the p40 in a training incident.. also If anyone has any pictures of p40 nz3115 it would be muchly appreciated.
