Replying to Look Pivot Bindings (identification)

Alright so i go to my local goodwill and i check out the skis as usual to see if anything good popped up. Lo and Behold, 2 pairs of look pivot bindings. They are really old pairs though, none of the new ones. i recorded some letters that i thought were the model or something
they are:

Look XM
and
Look SP 69

I want to know if these are still worth something. If any other info is needed, just tell me, ill go back and tkae some pictures and write down more stuff.

Thank you in advance!
