1886 Winchester in 45-70 Rifle

I have a 1886 Winchester in 45-70 that I think I will hang onto and likely pass it on to a grandson one day. It was made right around 1906 and my grandfather purchased it used in the 1930s. In 1969, my grandparents came up from California by train to visit us in Spokane, Washington. My dad had just returned from a one year tour in Vietnam. My grandfather gave my dad the 45-70 and I got a Model 94 in 30-30. I still have that too. Some time in the 1990s, my dad started giving me his guns, so I am now the third generation to have the 45-70.
