Some fairly interesting firearms history can be found in this slide show about 5 guns that truly made, if not changed, history.
See it here: http://www.mandatory.com/2012/05/13/5-guns-that-changed-history/?ncid=txtlnkusaolp00000058&#photo=1
Make sure to click on "more" on each page to be able to read everything they have on each of the guns.
All the best,
