This is an authentic 1970 PZL-Mielec TS-11 bis B 'Iskra' jet trainer, one of less than five hundred ever built.

Unfortunately, the Czechoslovakian Aero L-29 Delfin beat the Iskra for that selection, and the "Iskra" ultimately saw little use outside its homeland.
Here is that rival Delfin, of which over 3,500 were built:
Both aircraft recently photographed at the Planes of Fame Air Museum in Chino, California, by yours truly. Planes of Fame actually has two Delfins, the other one however is unrestored.
