A 5D Mag-Lite with the TM bezel and a post-TM bezel 6C. The 5D is slightly longer than the 6C. These are the only Mag-Lite flashlights I own that have aftermarket covers on them. The cover makes a C-cell barrel feel as thick as a D-cell barrel. I got the 5D at an estate sale and the 6C was on craigslist.
