I'm sorry, but even if you didn't include that last pic, I'd still say it's from FS.
The first pic is from the default b737-400. And as an avid 737 fan, it's easy to see differences between the FS panel and the real one.
1) The FS panel lacks the autopilot/Autothrottle indicator lights
2) The MCP panel is not really accurate
3) night lightning will give the cockpit a warm yellowish color, not grayish
4) The gauges lay out is not correct in FS
5) Ligh test switch is missing in FS
And this is just the differences between FS and newer 737-400 panels. The first 737-400 panel layout differs much more from FS
