Yeah it's 100% a 550F loom, you made a small mistake on the listing Al. Pic 3 shows the wires that fit near the coils, in that pic you can see another branch leading off which is for the handlebar switches, however you don't show those wires and move onto the next branch where the points wires come off.
Just thought I'd mention that.
The loom didn't come with the red label but did still have the cloth Alans-Electrics label still attached which is how I knew 100% that it was yours.
