Browning, Remington
They were all made from 1949-1958 so they are date code stamped on the barrel, see related links.
Several, the auto5, B2000, B80 and others
It is a St. Louis Browning made by Remington for Browning. It was made around 1940. It's value is probably around $250.00 without seeing it. The B means it is a 12 gage. A was 16 gage and C is 20 gage.
Impossible to answer without a detailed description and the serial number.
I think your referring to a model 11, made from 1905-1947.
Please explain what you mean specifically by "Pattern"
Have one that was made in 1943

Hi, i have a remnigton 12 gauge semi automatic mohawk 48 and i think they were only made for 4 years in the early 60s or early 70s. As far as price i have heard of people buying them right around 200 dollars. Im really not to sure about the 20 gauge you might want to take it to gun appraiser.
