Okay guys, I've got good news! I have located some more resources. The Suomen Illmailumuseo (Finnish Air Museum) has a pretty well preserved cockpit on their Po-2. The only thing off are a few of their gauges. However, the rest of the cockpit is in very good shape. THey're going to send me low-res pics to see the shape of the cockpit, but if I want photos of it myself, we'd have to pay 2.50 Euros per photograph. I don't have the money, but if we need resources, this is the time to get it.
