Sailplane question

[BJC]

This post:

Dick Johnson used cheap automotive motor oil, with food coloring added, for his sailplane flight testing. In the photos accompanying his articles, you could see the laminar, transition, and turbulent zones pretty clearly.

reminded me of a Thanksgiving visit to Tullahoma, TN, circa 1982. A local glider pilot had just taken delivery of a new sailplane, and was assembling it for the first time. There wasn’t much wind, but it was too much for the pilot and his helper to be able to get the outer wing panels inserted. My college roommate was visiting, and he and I assisted with the assembly. The pilot was Dick Butler, but I’m not certain of the glider. I think that it may have been a Nimbus III. It wasn’t clear whether Dick owned the sailplane, or was just going to be flying it.

Can one of you sailplane pilots identify what the sailplane was?

Thanks,
