What is the cockpit shown in this picture?
The cockpit shown in the photo is of a Boeing 747-400.
You can tell that it must be a 747 by the fact that it has 4 thrust levers (so 4 engines) in the typical Boeing design. The 6 screens with the EFIS controllers rule out anything older than the 747-400 (like a B707 or older B747 variants). The large gear lever with the 3 positions rules out the new 747-8 variant.
Here is a cockpit picture for comparison:
