Sven,
The right outlet is one of the "grocery store" GE's. The terminal design in these is kinda on the unique side.. There's one terminal on each side, but under the terminal are 2 small pieces of brass (one on each side of the terminal).. The idea was to place one conductor under each side, straight in with no loop. Pretty cheezy design IMO.. & once the tabs are bent down, they don't loosen up again to reterminate..

There are 3 conductors entering through the back KO's, The one on the right outlet is some sort of extension cord (16AWG?) & the red wire thats kinda hidden on the left outlet is switched.. the neutral is stranded 12 TW.. The customer didn't have time for me to really get into this, so I just capped everything here & installed a 2G blank until she calls to have this redone properly... Im curious to see what's going on behind the J-box.. but then again.... [Linked Image]
