Help - Glider Copilot Wing Authentic?

[Mtnman]

Hi guys, I've seen a few different styles of this wing. The backing on this one has the grid pattern and the threading is not frayed like the Middle East remakes. Has the angular style of threading to create the circle around the G being typical of These Wings. I thought I would give it a try but wanted to run it by you as my knowledge is limited here. Thanks so much for your time
