I have just brought a crazy looking spear gun from E Bay. In anticipation of its arrival I wonder if anyone has any idea what it is all about? Spear is underneath, looks like a sight is viewed through the barrel, how does the trigger work upside down? a fishing reel! I thought it might be designed to shoot out of water, maybe aimed at Carp from river bank or something? Cant imagine it will be much use to me? but I just had to have a close look (more money than sense) Thanks Mr X for putting me on to it!
