Campagnolo Racing T Square Taper 175mm Triple 52/42/30t Road Bike

(MISSING MIDDLE POSITION RING), Campagnolo Racing T Square Taper 175mm Triple 52/42/30t Road Bike Crankset. The crankset was mounted but never used looks NOS, tiny scratches from storage. Any 8/9 speed Triple ring,135 BCD spacing, 40-42 tooth chainrings will complete this crankset. This set is so new a brand new or very low miles chainring would be best to make this set work. I have seen middle rings for sale on ebay for $70-ish or online to make this a complete set.
