In order to answer your question I would need to know if your shotgun is a auto-5,browning pump shotgun(BPS) or a over-under(CItori or superposed)to give you a accurate answer?
e They are marked on the barrel.
It will be marked on the receiver/barrel.
Browning did not offer one, but you may find an aftermarket Hastings barrel (www.hastingsbarrels.com) that will do the trick.
Yes
Factory, aftermarket or NFA?
Look on the receiver and barrel.
The barrel exchange will be your best bet if you called browning this is the place they would refer you to. They are located in Ga.
NO! The 1187 barrel was for remington shotguns,the auto-5 shotgun is a browning shotgun.
This gun was made in 1947
Have it examined by a gunsmith familiar with A-5
It will be marked on the barrel or receiver regarding where it was made.
