I recently acquired a Kofod Larsen Spear Chair. The chair seems to be in good shape except for the straps which have been taken off and replaced with straps that were stapled onto the frame. Those need to go but where can I get the straps with the dowels to replace them? AND once I get them how are they installed on the frame? Straps with a loop on them or straps wrapped around a dowel? Also which straps? Pirelli or Fagas? It's hard to find photos of the original installation. Any help is greatly appreciated.
