The fact is that computer communication, an opening up of information sources in some countries, a vastly increased collector interest in finding information (probably part and parcel with computer communication) has meant finding much new information from primary sources that generally was not available years ago. We are all learning more about things, and sometimes what we are learning contradicts the “common wisdom” of the past. I don’t find it unfortunate at all; it is simply the natural order of things as more and more research is done, and I think it is common to many, many subjects, not just ammunition.
Older publications, for the most part, did the best they could with the information that was at hand. How many of us knew anything about factories behind the “Iron Curtain”, for example?
Some years ago, when I wrote a very large article on the 9 x 25mm Mauser cartridge, I was unsatisified that some initials that appear on certain DWM cartridges, and Greek cartridges, had been “unknown” all of my collecting life. Since it was certain, in my eyes, that there was Greek connection, a few days of banter on the computer betwen the great Swiss/Greek collector Dimi Goulas found the answer in a military/police museum in Greece. The same process would have taken months if not done over the computer, and perhaps no answer would ever have been received. There certainly had not been one up to the time I started asking questions.
I don’t like computers, I guess because I am extremely ignorant of their operation, but they have made information gathering thousands of times easier than it was even 25 years ago. Whether in the main, that is a good thing, is a matter of opinion, of course. Certainly it is when it doesn’t apply to personal information.
