Many thanks Stig for the additional photo of OO-AUI. This is the key to unravelling my question as you can make out the lower half of the serial on the rear fuselage confirming its exact identity.

Pieter summarises precisely the same problems I was experiencing with these and other photos of the burned out DC-3. But Chris Goss pointed out the partial serial OO-AU remaining on one of the shots of this one. So, given the exact match in camouflage pattern, plus the distinctive chimney in the distance in some photos, I am now reasonably well satisfied that we are looking at the same machine which landed intact near Arques on 23 May 1940 and subsequently became burned-out.

Thank you all for your input.
