SZD-19 Zefir 2A in USA?

The Zephir in the video from Argentina is based at my club. It was one of the gliders that the Polish team brought for the 1963 WGC. I think there were three and they all stayed in Argentina but this is probably the only one still flying. The present owner did a complete restoration job and it looks and flies very nice. Years ago the flaps were modified so they could lower completely to a landing position and not have to depend on the tail chute. The Zephir has no spoilers so there are some interesting anecdotes about when the tail chute failed to open.. The problem with the landing gear in the video was the gear light switch that got stuck. The gear itself was OK.
The same guy also owns a PIK 16 Vasama that flew in the 1963 WGC. It appears in one of his videos.
