Was visiting a CWGC cemetery at Pihen-le-Guines yesterday (near Wissant/Calais) with a friend looking for a relative's grave. There were some graves in the communal cemetery, but also a CWGC extension. Mainly RAF and all its national variations, with many nationalities represented. However, a few naval types including one (whose name I didn't note) but who was RNVR. Normal thing is for the ship's name to follow, but with this guy it had the initials above - 11th (?) September 1946. Tried a search for the initials, with no joy. Any ideas ?.
