The MD was missing its hourmeter when I restored it, so I bought one in a parts bin this year at RPRU for $5 and fixed it up.
Here are some pictures of the process. This one was made by Stewart Warner, but Veeder Root also made the same style of mechanical counter. I assume their mechanisms are very similar in design.
There isn't much info about these on the web, so hopefully this helps someone out in the future.
