The cockpit from the D-XXI in the Military Aviation Museum is close, but still has some annoying errors. The cockpit you can find behind both links OBIO gave you are all Finnish. Which had a totally different lay-out.
There is a wellknown picture from a Dutch cockpit, however this is taken from the prototype, which didn't have the (Dutch) standard cockpit......
I'm afraid there is a lot of confusion, but I have just e-mailed you with some things which might be useful.
The most authentic however is the cockpit from the wreck in the Crash museum and it is still quite complete. I do have pictures from that one as well, but I first I have to see whether I can find them......
Cheers,
