The vent rib breaks up the heat waves that rise from a hot barrel which interfere with sighting.
For the most part, the high standard victor was made from 1971-1981 depending on the features. The 4 1/2 and 5 1/2 in slabbed sided barrel with the vented steel ribs were made from 1971-1973. The 4 1/2 and 5 1/2 in barrel solid aluminum rib were made from 1973-1977 and the 4 1/2 and 5 1/2 in slabbed barrel with the vented aluminum ribs were made from 1973-1981.
