Just had a reply from Air Salvage, which doesn't look too hopeful. I'm after hoseclips, linkages, bellows, hoses. All the bits which are probably 'use once'.
I will write back to them, but does anybody else have any ideas? The motorbike builder was able to pick through all sorts of scrap, and was able to show me the Tornado pedals, etc etc.. That's the sort of stuff I'm after, as scrap, not ephemera.
