Rick,
As Clint points out, Perl was lost off the Durham coast in July 1940. The Volksbund Deutsche Kriegsgräberfürsorge lists Gefr Joseph Perl as missing over the North Sea on 19.07.1940. The same site lists only two 1941 losses with the name J. Perl: One of them was lost in Russia; the other in the Western Desert.
