Shotgun barrel that has a raised rail (rib) that runs the length of it. Here is an auction site with pictures of a shotgun with vent rib barrel. http://www.gunbroker.com/Auction/ViewItem.asp?Item=80157268 on a firearm it is a raised bar above the barrell
The barrel heats up when the weapon is fired, thus the sights becom off center. The ventilated rib is above the barrel and has air cooling the bridge the sights are on, so it keeps it more accurate.
The vented rib helped to break up the heat waves that rose from the hot barrel to improve sighting.

No

The Winchester model 1894 rifle was never made with a vent rib barrel! the only Winchester made firearms with a vent rib barrel was Winchester shotguns.
Your gun was made in 1960. It depends on the barrel length and with or without rib. Specifications from Browning in the 1960 catalog states the following: 26" plain barrel 7lbs 1oz / 26" Vent Rib barrel 7lbs 7oz 28" plain barrel 7lbs 5oz / 26" Vent Rib barrel 7lbs 9oz 30" plain barrel 7lbs 7oz / 26" Vent Rib barrel 7lbs 11oz
The vent rib breaks up the heat waves that rise from a hot barrel which interfere with sighting.
Between 340-550 dollars depending on the amount of original finish remaining,and what type of barrel your shotgun has,plain,solid matte rib,and vent rib barrel.The vent rib barrel will bring the most money,the plain will bring the least amount.
A vent rib is a metal sighting plane attached to the top of the barrel from the receiver to the end of the barrel at the muzzle. They are usually a quarter inch wide and may have small grooves along the top. The venting means that it is raised above the barrel slightly to allow air between the rib and the barrel which helps the barrel to keep cool. "Factory" simply means that it was originally installed at the plant that manufactured it. In trhis case either in Belgium or Japan. Many times aftermarket vent ribs are installed which hurts the value of a gun rather than increase the value. A factory installed vent rib increases the value vs a plain barrel.
Yes.Your Browning flat knob light weight auto-5 shotgun could be had with either a plain,or vent rib barrel.
