We are looking up the same info and I came across your question. It is not model 11 that is a roman numeral ii or 2. This info may or may not help you.
Give more info (model number) and ask again.
what type of shotgun is this
It your shotgun a Model 37-S or 37-T ?
In order for me to answer your question,I will need some more information from you.First is this shotgun a semi-auto,pump action,or over-under shotgun.I will need the model of shotgun.Then add the shotguns gauge(12 gauge,16 gauge,20 gauge)? I will need the serial number of your shotgun to date the year of manufacture.If you provide this info,I can then tell you how old your Browning shotgun is.
It all depends on the grade/model/gauge of the gun as well as the condition. More info/photos would be helpful.
The only info I have on the stevens model 94 shotgun is that it was made between the years 1926-1945.
Check your info and re-post the question, I don't believe there's such a thing as a "model 2"

12 gauge winchester 1900 made in 1899.In order to assist you in defining a value to your Winchester shotgun I will need to clarify some info provided and ask that you give a more detailed description of the shotgun in question.First I will say that Winchester made the model 1897 pump action shotgun,they made a model 1901 lever action shotgun in 10 gauge only.They also made the model 1911 semi-auto shotgun.So you must determine the model of your shotgun first.Then provide more info on the overall condition of the shotgun to include the amount of original finish remaining on the wood and metal,type of barrel(plain,vent rib,solid matte rib).All these things will help me assign a more accurate value to your shotgun.
