You did not provide the serial number.
Not unless it is threaded for them.
No way to answer since you did not give the serial number.
I would need the type of browning shotgun you are asking about,and a serial number which you did not provide.
Your question is about the Browning auto-5 shotgun.The age of your Browning cannot be determined without you providing a serial number for your Browning.
What is your question?
No such model made.
