Though...I didn't end up with a Springfield 45/70 😆
Also have a John Buckingham 12 ga hammerless Damascas barrel shotgun, it was my dad’s grandfather’s. That is another project, It functions but the breech latch has some looseness because of wear on a square bolt inside the action. And it has a broken firing pin on the right barrel. It was pretty modern when it was made. Knowing the ownership, it was somewhere between 1889 and and 1924. (my guess is between 1915 and 1924)
There are proof marks to look for and bore of chamber is another indicator.
So I have old projects and I have new builds. smile.
