Roughly the transition happened somewhere 1975-80 I would say. Also considering your toptube shows brazed on cable guides I would almost think your frame had shifter braze ons once. Edit: I realize one of my own frames has the combination of brazed on TT guides and clamped shifters too. A clamp for a 1990 bike I would still consider a real oddity.
