Gary Burns now owns this Otter. He has restored the "Normandy battle damage". I am using quotes as Gary noted that this Otter is fitted with an extra latch to keep the doors open. He analysed many photos and concluded that only the post war Dutch ones have these latches fitted. So, it is more likely this Otter was damaged on a Dutch range, rather than in Normandy...
I looked at a few photos and I think Gary has proved the French owner made up a story for his Otter. Anyhow, it is now in good hands
and is under restoration.
Take a close look, these Otters have a latch to keep the doors in the open position:
Not all Dutch Otters had them, though:
