1919
Need a model, serial numbers are not unique accross rifles. RW is Remington Works
First year 1909 (RW is not part of the serial - it stands for Remington works)
1920 RW isn't part of the serial, it stands for Remington Works.
RW isn't part of the serial no, it stands for Remington Works 1915
RW isn't part of the serial it's Remington Works Made - 1910
RW - Remington Works, they all have that stamp. That was made early in 1917 so there will be no other date code on the barrel unless it was later replaced (after 1920).
It was made in 1914 and that's not RV it's RW for Remington Works.
