Got a Stevens mod 85, 410 bolt action detachable magazine. Guy said it was broke. Looked at it and saw that it was missing one of the extractors. Paid him a few dollars for the gun. Took the remaining extractor out and made a mirror image of it out of a hardened nail. Matched the spring put it together. Also did a complete refinish on it (cold blue) and stock refinish. Showed it to the guy I got it from and he did not belive it was the same gun. That was 25 years ago. Have used it extensively ever since.
