i have these 4 'old stock' Raleigh gear-change cables in grey outers.
as can easily be seen from the 2 images they have been stored away for several years, some times coming out for a visit to a auto-jumble.
they are all in usable condition, but the ends have a coating of light corrosion on them, the inner cables have a small amount of light rusty on them the outers just need a simple clean over & the inners require a covering of oil some of the outers with corrosion could be removed for re-plating or just leave as is, maybe applying a coat of light grease for protection etc.etc.
PLEASE VIEW THE IMAGES VERY CAREFULLY ~ AS THIS FORMS PART OF THE DESCRIPTION..
many thanx dave..................
