Used, in very nice condition, early-mid 1970s. One front, one rear. Brake pads are dry, but are original. Original traverse cables included, and cable yolks (one missing washer and nut)
Both calipers include their frame mounting studs, but no hardware (nut, washer and those concave washers that match the contour of the fork and rear brake bridge).
