A Censor's Stamp, signed on 12 April 1944 by Lieutenant Clifford Gwinnell, appears on the back of a photograph of HMS Rushen Castle which he sent to his wife.  The photograph is the same as that shown in Rushen Castle (S5) - TWAS Ref 2931.36.1780.RC7 - Tyne 1944.

My thanks to Mrs Gwinnell for forwarding this to me.  It serves to remind one that security in those days was of paramount importance.
