I bought 2 new surplus jump cases at knob creek today....Ok I am not stupid but how in the hell are these things rigged? There is a paded zippered part perfect for a long gun, but it folds out and I think you could make a HUGE bag for other stuff. And it has huge latches but I think it looks if there is other strapping or a harness? has potential to be a nice case and is brand new....is there a video or a diagram anywhere I might be able to figure ii out? Thanks, Bill
