To rework or not....Rare Luger???

So, I have been "watching" this.


Bill, what makes the difference in an "official" rework? I know that the orginal factory reworks are considered one thing. I mean, lets say a 1911 1944 .45 ACP, they were reworked many, many times over the years. I carried many that were Remington slides, probably from WW2. If they were released, wouldn't they be a rework?
