I have an extra wheel/ brake set up from Either a BSA or Triumph. It is the twin leader I believe from a '68 or '69 model. the chrome on the wheel is very nice, spokes are not rusted. The Dunlop tire is even in great shape although quite old (would not trust it on the road, maybe for display). Also is a set of fork legs that are not nearly as pretty and stanchions that are pitted (for reference).
I bought a setup like this for my '66 A65 years ago, moved to my my '67 A65. It was by far the best upgrade over the single leading shoe I could do to that bike.
Asking $650 for all.
Shipping my be a bent spendy for everything. I will be at the all British Car show in Dixon in Sept if you are somewhat local and would like to pick it up in person.
