I bought the set when it first came out, and when Simpson redid it, I bought one - I much prefer the Red version, simply because the editor liked to make comments and moved things around that irritated Sturgess, which I understand. I find that sturgess moved things to me better, but both books are amazing - although mistakes are found in every book, and he liked to use his guns rather than any body else, which I believe leads to a slightly myopic view of the variations. This is not uncommon in writing, because you need to do that to an extent - it was a reason that Dwight and I asked for examples from other collectors, to include a section on magazines (input from Don Hallock), section on tools (input by Col Lindsey) and other experts.
The main thing I didn't like about Sturgess is that he didn't add anything from Simson Lugers - we had up to dated information, and he simply ignored it. No idea why, perhaps he doesn't like my writing style (or Grahams)
and it was the same publisher that did our book?
