Do17Zs with large upper wing crosses
 

Hi,

I'm wondering if anyone has a clear image(s) of a Do17Z carrying large upper wing crosses during or following the Polish campaign? Good detail and relevent unit codes/insignia would be a bonus. I have only ever seen one blurred photo of three Do17Zs with outsized upper wing national markings but the aircraft are so distant as to be unable to confirm their Stkz.

Any assistance much appreciated.

Regards,

Paul
