RAF Walrus rescue mission dated 23rd September 1940

Hello,

A Walrus from a RAF rescue unit, flew a mission on 23rd September 1940 (afternoon)

Area of the mission : about 500 km West of Brest (48°50′ N – 10°15′ W)

Purpose of the mission : to pick up the crewmen of a Luftwaffe He 111 which ditched because of mechanical problem.

The mission was unsuccessful.

My questions : to which RAF rescue unit did this Walrus belong ? which forming of the crew ? which markings of the Walrus ? precise time of the mission ?

Thanks in advance

Pierre Babin
