421323 Sgt Insull

[HJ]

I recently bought a secondhand book 'Martin's Air Navigation' by C.W.Martin.[1942 edition].On the inside cover is the following written in pencil-

NZ 421323 Sgt Insull E J.
R N Z A F
5 Agar St
Strand
London

Presumeably the address is the wartime NZ Embassy?
Anyone any ideas how to trace?Have tried the NZ Fighter Pilots website to no avail.

Hugh, I imagine this is Elfric James Insull. I don't have which squadrons but (relatively unusually) he was awarded the American DFC.
