As Eric said - definitely Schempp Hirth.

For what it's worth, one of the most well known Standard Cirrii is
VH-GZR,
flown by Ingo Renner at the 1974 Worlds at Waikerie in
Australia, and the
subject of the movie "Zulu Romeo, Good Start". This is a Grob
build

Cheers,

Flies very well too, that particular Cirrus.
