Well, I contacted the place were I bought the crankset. The owner said up til now he didn't notice. He said he bought a number of the Victory cranksets from the same place. He checked the last three he had in stock and said one has the blank chainring and two have the "Brev" CR bolts. He offered to have me return the crankset and he would send me one with the "Brev" bolts and I've taken him up on it. I'm still not sure how the blank CR bolts ended up on the Victory crankset, but I recently bought and resold a well used Victory crankset with the blank CR bolts. Both these chainrings were dated 1984 and I am told that all the Victory cranks bought by the seller are the same year; 1984 was the first year of these cranks so one has to wonder if Campy made some change or if some middleman was harvesting the OEM CR bolts for a short time..
