Disassembling a 1920s Monroe model K mechanical calculator, part 9

This is the ninth part in a series where I completely take apart -- or as much as I can, anyway -- a 1920s Monroe mechanical calculator. You can get these from eBay very easily, but most don't work well or at all. The idea is to take it apart to see how it works, then fix the broken parts and restore it to full working condition.
