The stamped number of the BB bearing cups would have given you the threading information that could also close to determine what region of the world the bike was made in... The 68mm width is pretty typical, not sure about the 34mm measurement....
126mm dropout (6/7 speed) spacing measurement at the rear indicates the bike is probably from the early to a little bit later than the mid 80's
