I read Gale Morgan's article, and summerized out this equation:
professional restoration = build up edges and corners
From his article, most important, he's very experienced and he knew what can be fixed via TIG welding, what does not worth the effort and he just cut it away and weld a replacement on it. That paper implied he did not have factory blueprint either, but he measured from a good one (not exactly the same variation, but close enough). And he had a bunch of parts guns to donate organs, original guns for reference, ....., his summary of German gun finish was accurate to the home "crisp but not sharp, smooth but not over polished" (not exact words, I don't have his artcle at hand)
