Without any more information, you question is almost impossilbe to answer with any real degree of accuracy. Value will depend on where you live, how bad you want to sell it, condition, finish, accessories, box, papers, engraving, what choke it is, barrel length, detailed description of all markings, stock wood, etc.. You could be in the 100-1000 USD or more range.
Browning never made a Model 51 shotgun.
If you have a 12 gauge model auto-5 Browning shotgun?Then it was produced by FN of Belguim for Browning in 1923.If you have the same shotgun in 16 gauge,then it was produced in 1928.
If your over under shotgun was made prior to 1964,then the model of your Browning shotgun should be named the superposed.
No browning did not,but winchester made a ranger model pump action shotgun.
No
Can't answer about "Volunteer" question. Please tell which model. Volunteer is not a model by Browning
I would need to know what model of shotgun we are talking about before I can say when your browning was made.
If your Browning auto-5 shotgun is a 12 gauge model then it was made by FN of Belguim for Browning in 1907.If you have a 16 gauge model,it was made in 1921.
In order for your question to be answered correctly,you must include the model of Browning shotgun in question,along with the serial number.Also include what gauge of shotgun you have.
Auto 5
Need a full description of all markings.
I have no records of a Browning 16ga shotgun having a A prefix to the serial number.Please check and list the model number(or name model) of your shotgun in your next post.
