The answer to your question is yes.The browning lightweight (light 12 or light 20)could be ordered from FN with a vent rib barrel.These browning lightweight model auto-5 shotguns were made between 1967-1976.
Need a detailed description of finish, condition, box, papers, all features and markings.
A letter from Browning will remove all doubt. Could be 57 or 67
If gun is mint and never fired - then you could reasonably expect $1500 - $2000 auto5man
That sn goes beyond published data. You will need to call Browning.

Yes.Your Browning flat knob light weight auto-5 shotgun could be had with either a plain,or vent rib barrel.
This is a mixed question. Which gun do you have? An Auto-5 Light twelve, is not a pump shotgun, it is a semi-automatic. Since 1979 is before the Browning Pump Model BPS was introduced, It is assumed you do have an A5. Value depends on condition. Typically with average use, these guns sell in the range of $500-$750 depending on condition. Mint in the box will go $1000+, but remember that this model has a fixed choke in 1979 and won't bring as much as the later Janaese made Auto-5's. The nickel plating you mention is not Browning factory finished. Browning never plated an auto5. You could have a silver receiver that was custom engraved, but it wouldn't be plated. If someone actually did nickel plate the gun, it could decrease value.
Please check the serial number. It is believed that the second digit is the letter "G" and not the number 6. If this is the case, you have a Light 12 made in 1967. Value depends on condition, meaning how much of the original finish is remaining. Depending on the condition of your gun it could be appraised anywhere between $400 and $1500.
You can purchase browing gun parts directly from Browning's warehouse and repair facility in Arnold, Missouri.
Answer Everything depends on condition and year of mfg. It could run from $300 to $1500 depending
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, etc.. You could be in the 100-1000 USD or more range.
