Reading back in this thread and revisiting the material collected on the Po-2 I noticed an interesting fact - the Shuttleworth collection apparently has chosen a colour scheme which already has
appeared here as well:
Here's another image of that scheme, from the material
brought up here:
You will notice that the number on the tail fin is identical to the Shuttleworth exemplar, identifying their Po-2 as emulating this particular Russian night bomber regiment Po-2. The actual airframe restored of course has a completely different history, as described on the
Shuttleworth Po-2 page. It would have been kind of interesting if the foundation had included a bit of the history of the aircraft they chose to emulate as well.
