This was about a week before ULTRA started yielding results from Norway but here's a Sunderland claim from 21 July, in case it's of interest:
2 Me 109 belonging to 8./JG 77 started at 0430/21 to attack a Sunderland flying-boat in area of Trondheim. One a/c landed at 0520, the other one was shot down and forced to land on the sea. The Sunderland was shot down at 0515. It fired red recognition signals. It was reported at 1000/21 that a/c had observed a rubber boat with 4 men, probably belonging to crew of Sunderland, Rescue had not been reported by afternoon of 21/7.
NOTE: All times are Norwegian times. (A)
