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
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.
