I have been thinking about doing a Loft, but maybe there is a easier way, Loft seems to be pretty straight forward. I am talking about the slope at the plate you can appreciate it better in the Detail BC
i'd draw out the main shape of it from top down, then boss extrude by the thickness. as for those 2 slopes i'd make 2 identical boss extruded cubes that represent roughly the shape of it, then do boss cuts in order to get it like that. let me put together a quick few screenshots.
in order (very rough sketches)

I went about this with a sheet metal forming tool. Files are in SW2013 format.
