Originally, the only braze-on was a RD cable guide atop the right chain stay, and the stop which you can still see on the bottom of the downtube for the single Campy RD lever clamp. All the clamps were Campag. which eventually got rusty and dug into the paint anyway. The restorer replaced the BB and toptube cable guides which a frame builder add ~1990 because they too had rotted. The frame also needed other repairs.
