k bought the skis and bindings for 25 dollars Paul.Mind if I ask what you paid? Cause poachers with p18s is an insane thrift find.
Just from a visual standpoint I wouldn't call those very beat. Sounds like you have some dirt under the turntable which is making it hard to turn, just rinse them off and spin them around until you get everything out from under it. The cracked half moon will need to be replaced before a shop will mount them again,
slopestyle.com sells them. As schoess said check the metal ring on the baseplate for any cracks, if you see any youll want to buy new brakes. Also please be careful fucking with them, if you put your finger in the black trapezoid support post thing and engage the heel you could break your finger. Refer to
