metal folding in?
Thanks Peter McGrath for the blowup of the 'golf club' - now clearly a strap of some sort.
However, the blowup did show something else interesting. At the far right the metal panel edges are bent *in*, not out. The whole metal flap is obviously pushed out, but the actual edge has been rolled inwards with a semi-circular profile.
Peter, could you perhaps blow up that section and post?
