I don't think this is a military term. It seems to refer to the finish used on the Rib that runs along the top of a Shotgun.
Iver Johnson made some Westernfield matte rib 410's
With all original parts and 95% original finish, plain barrel = $625; matte rib = $825; vent rib = $950.
That cannot be answered without you giving a detailed description of your browning shotgun overall condition,and barrel type(plain,solid matte rib,or vent rib.)
That would depend on the type of barrel with the shotgun(plain,matte solid rib,or vent rib barrel)if a poly choke is present on the end of the barrel,and what condition the shotgun is in.
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.
That would depend on you providing the overall condition of your shotgun,and include the barrel type(plain,solid matte rib,or vent rib) barrel.These are needed to establish a correct value to your shotgun.
325-375 dollars for a gun with a plain barrel.375-450 dollars for a gun with the matte rib(solid) barrel,and 475-550 dollars for the model with a vent rib barrel.
Nothing without you providing a detailed description of your shotgun,to include the model,serial number to age your shotgun and what type of barrel it has(single,double,over under etc.)also include if it is a plain barrel,solid matte rib,or vent rib barrel.
If we are talking about a browning auto-5 shotgun?Then the value is running between 350-550 dollars,depending on overall condition of your shotgun and the barrel type(plain,solid matte rib,or vent rib barrel).
Your Browning which was made in the year 1947 will bring between 350-550 dollars,depending on overall condition,and a good bore.A vent rib barrel will bring more than a model having a plain barrel or solid matte rib barrel.
