And, thank you, Bert. I will check with them, but I am not sure what they will know. Maybe someone there remembers the style of drag chute connection?

Best suggestion ever, Bert! Our soaring community never fails to impress me in good ways. The message has been forwarded, as most students at the Akaflieg are likely children, or maybe even grandchildren of those involved initially with the project over 50 years ago. However, the message has been forwarded, and I am in contact with owners of other SB7s, and have leads and information to share on this interesting sailplane.

PS: Anyone have an Ilec SB7 vario they would like to donate to an SB7 sailplane? :-) Mine currently has a Cambridge with a speed director and a 10 m/sec. log scale winter vario.
