You will need a replacemetn barrel that is rated for steel shot.
While the original length is not indicated on the barrel, the barrel weight is. Example: 1Kg012 which would mean 1012 grams. An accurate scale would help you identify. If the barrel weighs less than the stamped number then the barrel has been altered.
Have it examined by a gunsmith familiar with A-5
If you own the browning light 12 with a plain barrel then 340-450 dollars based on the shotgun having between 60%-90% of its original finish remaining.If you have the vent rib barrel then 415-630 dollars.
800 or so
Although both are interchangeable, a true Sweet 16 barrel will have three holes drilled through the barrel band. This was one of the ways Browning lightened the barrel. The rib will also be a smidge thinner than on a regular barrel.
You will have to ask Browning.
The buck barrel is not original to guns in the 50s. Use the link below for value. http://wiki.answers.com/Q/What_is_the_value_of_a_Browning_Sweet_Sixteen
This is a standard weight 16ga auto 5. It was made in 1962. The barrel should read: Browning Arms Company St. Louis Mo. & Montreal P.Q. If the barrel only reads St Louis and not Montreal, then the barrel is not original to the gun when it was sold.
Depends on condition and whether it has the original box and papers.
