I would need to know the manufacturer of your 77B shotgun to be of any help to you.
The letter I think
I would need the type of browning shotgun you are asking about,and a serial number which you did not provide.
You will need to find out who made it first.
You need to find a gunsmith.
You will need to include the model number of your Winchester shotgun,along with the serial number to get a accurate year of production.
You will need to call Browning.
I would need more information on the gun but can come within a year or two. If you email me I can discuss the gun and then post info about your shotgun. jmann@worldpath.net Best, John Mann
