Hello,
Have used "Paint" to enlarge the picture and I think that I can now see "P2" and a "5" but in between is faint.

So if the a/c in Squadron letter for P2335 is known to have been "M" then it just might be the one.

I have looked in "The Battle File" 226 Squadron and found the following (which I am sure you already know but just in case).
