This SM-2 flew with the Polish AF from January 1963 until August 1976, after which it was used as a ground instruction frame at Warsaw-Bemowo. It was preserved at Lodz - Lublinek (LCJ / EPLL) before ending up in this hangar at EPGO. I believe it has since been moved to the Muzeum Orla Bialego (White Eagle Museum) at Skarżysko-Kamienna (which is great news).
