I just happened upon this site: http://candrsenal.com/ They have detailed pictures of many of our favorite surplus military rifles and pistols. They have dissected views, full views, and sight picture views. Excellent photography, and able to order them as prints to boot. Here's a sample of my favorite battle rifle, the SMLE No4 MkI* I will be ordering an anatomy print (maybe the other two, also) of the No4 MkI as soon as I figure out how much and how to order from them. They are kind of vague on their website; I believe you have to go through their facebook page or something. I'm still looking into it. I wish they had this site back in the day when I owned a pair of Mauser C-96's. Learning how to reassemble them was a chore and a feat.
