Old ones, from times when I was running around with K-50. Krakow Aviation Museum (only one in Poland dedicated to aviation).
K-50 + DA 35mm 2.4, Pentax Natural colors (set in DCU)
PZL P.11c, flyable but I doubt anyone would risk getting in into air as this is only one original left. It is taxied in museum from time to time to keep engine in good condition.
Celier Xenon, polish build gyrocopter. I think version 4 is still in production if you want one :P
Jakowlew Jak-23
I am not really sure about version, this is Suchoi Su-7, I think it is BM version judging for the undercarriage look. It was one of two version of Su-7 used by Polish aviation to carry nuclear weapons (yeah, Poland had them from USSR, good times :P).
Something from USA :P
Mikojan-Guriewicz MiG-21MF in occasional "gold" painting
Tadeusz Sołtyk TS-11 Iskra. In the foreground and just after (in camouflage) TS-11 bis DF, training and recon version. The white-red one is TS-11 bis B, trainer for live ammunition (with 4 points to carry weapons).
