@Austriarules, as @rjs, states they are RC4 SC and not SL's. They look very very similar, but the on a distant view the SC has a round C near the tip, whereas the SL has a more defined L near the tip, the back looks the same. The Sc have a racetrack binding but the sl has a plate. You may get a rather cross buyer and get them returned.
Had a pair of SC, nice skis but I could not get forward enough on the racetrack bindings as I have very small feet, so swapped them for a pair of rossi.
