According to Mason’s ‘The British Bomber’, 455 used Hampdens at Swinderby from July 41 until April 42! Not that it matters, it’s certainly wrong for a Mossie.
And yes, Happy Christmas to all.
After that, they went over to Coastal Command and continued using the Hampden at Leuchars and briefly, the USSR, before re-equipping with the Beaufighter in 1943.
The Australian War Memorial has an online copy of the 455 (Australia) Squadron ORB. It’s well worth a read.
