Hi Steve,
Let me share a good news...

Following the tragic death of Janusz Karasiewicz, the manufacturing of Jungmans/Tatras stopped in Poland.
Now the company "Serwis Samolotów Historycznych" (Service for Historic Aircraft) is back on track, led by Janusz's widow, Jolanta Karasiewicz. The company has a website, presently in the Polish language: www.planeclassic.com

Please find enclosed a link illustrating the first flight of the newest Tatra:

Mirek
