1965 World Championship

Does anyone have a copy of the S&G report on the 1965
World Championship held at South Cerney in the UK?
Markus Ritzie, of the Swiss Team, flew a Standard Elfe
to second place in the Standard Class. I know he flew
my Elfe S-2 (then registered HB-801 and carrying competition
number 74), but I want to establish whether this was
his practice aircraft, or the one that he flew in the
competition. Martin Simons, in Sailplanes: 1965-2000,
states that the aircraft had a V-tail. HB-801 has a
conventional tail, with the tailplane at the base of
the fin. I have a copy of the August 1965 issue of
Soaring, but the report on the competition doesn't
give the aircraft's identification.
