Ditto... but it fits into my theory that the bikes are a mashup of early parts on a later frame. The centerpull calipers from a Sports Tourer (ish) bike would be too long for a Super Le Tour 12.2 frame. However, the front centerpull caliper would be the right reach for the rear of the Super Le Tour. A Dia Compe G sidepull caliper would be a cheap, available alternative with the right reach.
