I'm not a collector and I have a set of Fischer RC4 1984's 195CM. They are used but in good condition
where can I sale them and how much should I expect.
Actually here is another poster that says they are 83-84
You linked to post #3810 which doesn't make sense; if you mean Rossi Smash's post on the same page, that's a different ski than yours.
He has the 83/84 season "Super Competition SL" race ski, I think you have the 84/85 season "Competition S" recreational slalom ski.
I would be interested in Red Sleds if I didn't already have a suitable speed ski, but 205 cm just a tiny bit too short for my purposes. The OP's skis, on the other hand, are not so interesting. The bindings MIGHT be worth something if in good condition.
Have a close look at the very top of the pic - there's a faint 'Competition S' printed in between the orange stripes. That to me screams winter 84-85.
Also notice that OP posted 'RC4' not 'C4' - I don't think there's much chance of the OP making a mistake there.
