As always with Wikipedia, take it with a grain of salt. A number of anonymous authors have been working on this, representing a quite varied level of knowledge.
Just one example: contrary to what Wikipedia says, Rheinmetall did not own the brand name of Dreyse & Collenbusch in Sömmerda, because Rheinmetall bought the Dreyse rifle factory, which had been founded for making the needle gun and existed totally separate from the much older Dreyse and Collenbusch company.
There are other examples of superficial knowledge, posing a danger of contaminating serious research. Not to mention the lack of cited sources, which are a must in my view.
The Israel section is 1/2 to 2/3 incorrect.
The best proof not to trust just any source.
And also the best justification for the IAA to exist!
The best (and worst) part of Wikipedia is that it takes little effort to correct errors. If one is in there anyway, and one knows for sure something is wrong, might as well fix it. IMO. I lack the knowledge/proof to do so, alas.
