Well Zippy, looks like we are both trying to find a photo of Any Mk.Vb of 126 Sqn
Like trying to find hen's teeth! My GG Davidson met his fate in EP310 on 15th of Nov, '42.
Looks like the code during that time was "V" and I'll be dogged if I can find any with that code to give me colours or patterns.
Wishing us both Good Luck ay!
