It MAY- depends on which Browning and which Miroku. Browning moved production of some firearms to Japan, where they were produced by Miroku- so there IS some relation between them. Really need to check with a gunsmith, or staff at Numrich, gunpartscorp- with their staff.
The Browning light weight 12 gauge shotgun was made by FN for browning from 1947-1976.These shotguns were also made by Miroku of Japan from 1976-1998.If you would supply a serial number to your browning shotgun then I would be able to identify the exact year of production.
The Browning side by side (BSS) was made by Miroku of Japan for Browning from 1971-1988.they were available in either 12ga,or 20ga.with a barrel length of either 26in,28in,or 30 inches in length.I would advise you to contact Browning Arms Company for the exact date of Manufacture thru their customer service dept.
I would contact Browning directly and see if they have any in stock. I would also look at Boyd's rifle stocks and see if they have any reproductions that would fit your Browning.
100-450 usd
If you have a Browning safari bolt action rifle,then the year would be 1969.It should also be marked FN.
No action made of leather. If you mean LEVER action, that would be the BLR. 100-500 USD
A browning BL-22 grade I in 60% condition would be worth 150 dollars,A grade II would be valued at 160 dollars.
The only browning sweet sixteen,s made in the 1980,s were made by miroku of japan from 1987-1992.These would have a two letter code in the middle of the serial number,since browning went to this form of identification in 1975.Is it possable that the 6s is a prefix to your serial number of 49756? If so then you would have a belguim made browning sweet sixteen that was made in 1966.
I need to ask if this rifle was made by Browning?The 2 letters in the serial number would indicate that this rifle was made in the year 1998,as marked by Browning.Winchester never has used the serial number system that your serial number demonstrates.If this was a Browning made rifle it was probably made by Miroku of Japan and would be so marked on the rifle.
Your serial number prefix letters of RN indicate that your Browning 16 gauge shotgun was made in the year 1979.This would indicate that your shotgun was made by Miroku of Japan.All browning shotguns made after 1976 were made by this firm for Browning.All 16 gauge Browning shotguns chambered in 16 gauge were made before 1977.It sounds to me that you could have a shotgun made by Miroku of japan,and possibly have a Earlier Made barrel installed on your shotgun.A standard weight auto-5 shotgun will bring between 325-375 dollars in the condition that you describe,and deduct 30% for the poly choke barrel.
The value of your miroku will depend on grade and contition would range from about 750 to 1200
