That's a Gulf War 1 scheme Mike and that particular aircraft survives (in that livery) in a museum. Think it's at Duxford if the old grey matter is working.
The fore and aft lines on the upper wings are vortex generators.. a little over done if I may be so bold. The VG's themselves are small triangles designed to improve airflow around the boundary layer making low speed/high AoA control easier. On the paint above.. they're shown with lines of muck behind them giving the impression they're a lot bigger than they actually are

Yeah, the dirt behind the VGs is a bit OTT. I still like the model though. I've been tweaking various bits in MCX to improve the overall look, although in that pic the bombs still need de-shining.
