Stéphane Pennequin from Corsica has the most comprehensive museum of climbing gear in the world. He is still searching for some early examples of particulary rare nuts (and some not so rare) to complete his collection. He is doing an incredible job in collecting this material and collating the history of climbing protection before the generation that invented the gear we now take for granted disappears and it is especially relevant to British climbers as nearly all the early hardwear was produced in the UK. So dig out that box of mouldering Moacs from the garage folks - you could just have the missing item that he is looking for!
Check the link below for the full story and list of missing nuts.
