Homebuilt Touring Ski 175cm with Fritschi FR+

Homebuilt Skis with Fritschi Freeride Plus-size Medium for 27.5 boot. Skis are 175cm Tip 130 waist 100 tail 120 twin tip. BD Glidelight MIX STS skins to match-$200. This set up is hardly used and built by my father in law. He is done with touring.

I am willing to separate the bindings from the skis if you'd like.
Skins are sold already sorry. 
 

What year are the bindings? How much mountain time have they seen?
