I'm putting this rear two piece valanced guard out there on different forums every few months, hoping it will ring a bell? It has a normal cutaway for the chain guard, but another indent on the offside to clear something?? Someone in the world must need it? I'll put it on ebay if i can identify it.
Douglas I can't identify it exactly, but I would say that the the O/S indent is for the bottom frame tube. An M20 Valance is stopped shorter so no need for the indent. If it's BSA I'm sure Leon H. would recognize it. Ron
