Sure. My camera battery is empty, so the close-ups will have to wait, but perhaps these will work. The Gitane Diffusion de Grande Luxe (can't get enough of that name yet) has braze-ons on the down tube and the right chainstay to which the chainguard is attached. The Batavus uses clips on the down tube and the seat tube. As you can see, the clip on the seat tube, at least in this position, will not work in combination with a front derailer.
