First off, why do you want it restored?
A removal of the original blurring and or case hardening wil desirous the value of the gun.
If you repair and make function well the gun will be worth more as a collectible.
I don't what you want?
It is survivor and few are around.
Right, well, there’s that, too.
My grandfather and his brother decided they wanted a .45 instead of a .40 and tried to bore it out. It did not work. Farmers from Central Texas trying to be gunsmiths.
My father remembers them trying, so I guess it was attempted in the late 1940s or early 1950s.
It will not hit paper at 25 yards.
I do want it to be functional. Marlins of that era are not worth the same as Winchesters. I probably will not do a full restoration, but a 'bring it back to where I can shoot it' job.
I have a donor gun, but the donor gun is in better shape, so I may get them both done.
I remember playing cowboys and indians with it. I was the second youngest of 9 grandsons. All of us boys played with it a lot.
I am the only one who can afford to pay for it to be done, so I got it.
