Hi all, thought this might be of interest to some.. Everyone says all Sandcast and KO use the same forks ,....currently doing a diecast resto 12/69 and found front slider oddities , anyone have any idea when these slightly tapered at the seal area sliders came into play.? they are definitely  both pre K1,. obviously one has been changed at some early stage, pic shows both sliders from same bike, which one is correct ?  the  Brighton bike has the same slightly tapered ones. Both have identical internals.
