The aircraft features the typical twin red bands commonly photographed on Soviet MiG-21S's that participated in putting down the Czech uprising. The number is a non-standard blue with white outline four digit code.
I had no reason to doubt the veracity of the markings (they were from the Ukraine!), until a Google image search turned up several photos of blue 1611 on the airshow circuit:

So now I'm wondering, was this a real aircraft? Did MiG-17Fs participate in the Soviet incursion into Czechoslovakia in 1968? Or are the markings just spurious airshow markings?
As I've noted before, there is a dearth of decals covering Soviet numbering and markings for the MiG-17 or any of it's early NMF bretheren...
Any help is appreciated!
