My current project is an interesting ebay find. What caught my interest was the A50"B" in the engine ID. This is a '64 BSA A50 twin Cyclone competition - desert racer. I'm not finding much information related to how many of the Cyclone competitions were made and shipped to the US. Mine is fairly early with engine A50.BC.142. '64 twins started with number 101. Trying to determine how many were built and where mine fits in the production time line for this model.
