I did notice the broadarrow marking on the 'leg/harness' strap, but I also noticed the snap on the strap at the end of the case. It looks to be a pull the dot type seen on American kit. The stitching along th side of the case also doesn't look right to me.
I also have to ask myself wheter or not the single strap at the end would keep the rifle in the case upon parachute opening. I can envision a good, hard jolt sending the rifle right past the strap and on its way to terra firma.
