If that is the entire serial number, it was made in 1939. Value would depend on whether the gun is original or not, and its condition.

Sorry, the Light Weight Twelve was not made until 1953, and the gun was never made in St. Louis. Post the serial number and we can tell you what you have.
remove barrel and serial # will be stamped on top of receiver on left
I'm not sure if your trigger is new or if your serial number is wrong. The gold trigger wasn't produced until the late 50's once the Japanese produced the Brownings but your serial number would put your gun as being made somewhere between 1903 and 1939.
Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Auto 5's with recoil pads (other than Mag 12's) poly-chokes and compensators will reduce value. Recommend taking it to a gun shop for appraisal. FYI:Your serial number should be with the number/letter "1R" which designates that it was made in 1961. The Browning Co. offices were in St. Louis and Montreal. The gun was actually made in Belgium.
This is what is called an American Browning. These guns were produced by Remington in the US (New York) for Browning after Belgium was overun by the Germans in WWII. The guns were made using Remingtons model 11 equipment. A few modifications were made to incorporate more of the Browning features and were all stamped Browning Arms Co. St. Louis Mo. Your gun serial number isn't correct. The highest 12ga serial number made is B43129. You probably have one too many digits in your number listed. Please check and ask again. Thanks.
The S.T. DuPont lighter serial number 50 is located on the bottom. Each letter and number is printed separately so that each one differs.
