It's a bit hard to tell but it appears that your rifle may have "nickel plated trimmings" as the Winchester catalog referred to it. It looks like you are well on your way to making that old smoke wagon live again. Welcome to the forum!https://centerofthewest.org/explore/firearms/firearms-records/
That is a perfect , perfect , example of a 76 !!! you are a lucky man !! I really like the pics. of the ammo , can you give the " OAL " of the cartridge & ( guess ) the depth of the bullet ? And " Welcome ". coffee's ready ,, Hootmix.
Welcome BillKilgore , nice rifle and even better its a family heirloom . ,,,DT
That looks like a really good bore. Be sure to slug it. Should be a great shooter!
I need to read-up on how to slug the bore. Is this to confirm the bore diameter?
What a beauty , and a shooter to boot .,,,DT
