Thank you for bringing this model, and the publisher, to my attention. The old model of Po-2 (GPM I think) was due for an overhaul. This seems excellent and very tempting (see
publishers photos).
On the European scene, Slawomir Wojcik (
Kartonmodellbau.net) has already
reviewed it (in German).
The Po-2 was used by the "Nightwitches", women pilots who bombed the German invasion forces under rather heroic conditions. The model depicts the Polish version, but could probably be changed to a pure Russian version fairly easy (Photoshop the Polish insignia away), if one would prefer that.
For your inspiration, here's a
Babelfished translation from the MK Magazine, plus a drawing from the same site of different versions of the Po-2. The civilian one isn't bad either - I believe it had four seats and a wider fuselage. That would be kind of hard to accomplish, though.
