Books tend to print that is certain, and what is certain about surefires history has been reprinted over a course of many years, starting with their first catalog all the way up the 2009. Their history has been reprinted annually, no reason to waste additional capital trying out an experimental copy of something that already works.
As for model variations, old products have been discussed to bits, new products availability subject to change without notice, no point printing something that the company considered later in the future non-essential and omitted is there?
Besides, if Surefire does print such a thorough journal of every nic and pic starting from prototypes to production, model to model variances, model add-ons, etc...then it automatically becomes a hude company asset, and what then, shall Size15s do on the forum?:nana:
