AH, yes, could be French. I should measure the thread pitch and BB width to be sure. Also, perhaps a clue to its age is that it has no braze-ons at all, no cable guides of any sort. What decade does that put us in? 70's? Wasnt there a window of time after they started making frames with built in der. hangers and before things like over the BB braze on cable guides were the norm?
