Reconditioning Brake Lines

If it was me...I'd use the originals as a pattern and bend new using copper nickle brake lines. First straighten the new line by pulling a slight tension on them, then bend to match the old. Who knows what lurks inside a 50 plus year old brake line?? Is it worth it from a safety standpoint? I think if I was buying an old car and the seller said the brake lines were original, I would trailer it to my shop and not risk driving it home...just saying
