I've noted more than 130 Dolphins in Tambov - but no panic, I will not upload each one seperate :D
The black stripes under the cockpit where not on every, but on most of the Dolphins stored/wfu or scrapped there.
L-29 Delfin from company Blue Sky Service is ex Slovak air force tc. nr. 3405 (and before Czechoslovak air force) and after general overhaul has still the army c/s. Here is captured on landing during CIAF 2012 with display pilot Ing. Pavel Vesely.
