Ah, me… without my chequebook at hand…. Alas!

Just reading the description, it would seem that the aircraft is restored from various bits. The TBI instrument is said to date from 1942; the engine is an M-11FP (likely ca. 1950s); the air screw from 1954. The original rear cockpit components did not include any secondary controls, which would point towards a military version of some type (recce, photographic, or even a light night bomber). However, these items have been installed into this restored aircraft, causing it to conform to the basic training variant of the U-2/Po-2.

Looks impressive.
