This won't help much, but I commuted for a while on this very comfortable 1986/87 Puch 190. But this one was Puch in name only. It was a Kuwahara Japanese frame with stamped dropouts, but was double-butted steel and a quick, comfortable ride. Unfortunately I crashed it and wrecked the frame. Its most fancy feature was those classy Suntour shift levers. Those are now on my Motobecane.

The saddle angle was later fixed from this.
