In the book "Though Without Anger", a 437 Sqn loss on the 21st was promosing but the online ORB shows that all losses that date for this squadron were during a Market Garden operation.
But I found a candidate thanks to Google: the Dakota KG512 of 271 Sqn. See

"Though Without Anger" has the loss on the 25th of September with no detail at all.
A check of the 271 Sqn ORB could be useful.
