Hi,I have just acquired a bike from a mate who says that the engine is from a triumph 250 trailblazer and that the frame is from a bsa c15. The thing it I can't find any pics of the trailblazer (1969) which is apparently amercan spec. I have been told that the two bikes were almost identical but I would like to see both in detail so I can decide wheather to rebuild the triumph or the bsa or both.thanks for your help
