googles

Hi, do anybody know what kind of google that is? I can't find information. Is this piece rare?

Hello all, snow season is about to start in south hemisphere so I'm looking for replacement lenses. I have a pair of Flight Deck (Matte White/HI Yellow) but I want some darker lenses. I started looking for them but then I realized I dont know if my googles are "Flight Deck" or "Flight Deck XM"...
