O.K. What I did was I save each picture (page) in “my pictures” and then put each one of them through Paint Shop Pro X, the only picture enhancing program I have. All I did was move the “blacken” cursor as far as I could to darken it. Then, I printed them out. While it did not come out great, every page is completely legible. The whole procedure took about five minutes.
I doubt, though, that if I posted the improved scans here, that on screen, what I did would be of much help in viewing them in the size they would be. Anyone really interested in the report, as I am, can do the same procedure, and those with a good, sophisticated Photo Shop program can probably improve on my results.
I think you were smart not to continue with too much testing using a Gold Cup .45 of that early serial number. I am sure that gun had the lightened, cut out slide (like the early LW Commanders had), and if the recoil spring wasn’t changed, a compromise spring. I forget the weight of the Gold Cup spring, but I recall clearly it was shorter than a factory hard-ball spring, and perhaps a couple of coils longer than what most of us did with our NRA-Style target .45s for shooting light, hand-loaded SWC loads we all fired in matches years ago. I think a large diet of loads like what you show in the report would have battered the gun. Later, Colt stopped cutting out the slide. I would like to think they did it because they came to their senses about the purpose of the pistol (a full-weight target gun), but it was probably to save a few bucks in milling costs. I like my LW Commander .45, which I carried for about 17 or 18 years, but I fired it only enough with full loads to insure I could qualify with it and it was still working flawlessly, as it always did, right out of the box.
