Yes
500 or so
A browning safari grade rifle in a standard caliber,and the condition you describe is valued at 995-1,100 dollars.
Not unless the Smith is chambered in caliber .270 Weatherby- and I have never seen one that was.
100-500 or so
I was with my father when he purchased his FN Browning 270....it has the SN L3XX....so I would say yours is somewhere in 1959 to 1960 or 61.
Nice rifle
100-1000 usd
The full name of the cartridge is the .270 Winchester Center Fire. WCF. To distinguish it from any other .270 cartridge, such as Weatherby, Holland & Holland, etc.
A nice rifle that will give decades of good service.
Your serial number indicates that it was made in the year 1969.
According to the Weatherby website the twist rate is 1 in 10"
