Hi, always difficult to say for sure with these nets, but I would observe that the corrosion/wear to the clips appears much heavier than that to the net. As there seems to be very little transfer of corrosion from the clips to the net, I would guess that the clips are original ground dug relics and the net is a modern copy. Leon.
