I am looking for a polar curve for an SHK-1 (Schempp-Hirth, but from 1968!!!).
Can anyone help?
Dave McCormick

On page 21 of the February 1971 SOARING, Paul Bikle shows a polar for
what he calls an SHK-1 (N93174)

This is compared with tests of a Prue Std, which is pretty much
identical.

Available from the SSA Magazine archive.
