I found one interesting site, http://www.sp-2418.com that has a lot of Foka stuff for SP-2418. There is also some film form 1965 and 1968 worlds so you can see the Foka but there is also a lot of other gliders of that vintage in the film. Some shots of the Zephir and Bocian. http://www.sp-2418.com/filmy/ Not bad, winning Open Class with a Standar Class sailplane.
