Pair of Riley narrow track half shafts slight marks to one thread as per pictures. The half shafts look unused but cannot say for sure, These are the uprated type supplied by Vintage Riley Parts with the diff end induction hardened not to be confused by the cheaper ones that do not have the ends hardened.
Broken down. Not working. Could bake a working engine from the 2. Found in grandfathers / uncles garage along with large amount of other de Dion parts..
