Wow, what an amazing device! I’m surprised this isn’t better known in the West. I’d love to understand better how it actually worked in a detailed way. Mechanical computers are so cool.
If you're ever anywhere near The Bay Area, go do the tour of the Nike Base in the Marin Headlands. They've got a _super_ cool mechanical targeting computer there...
BTW, do you have any measurements of that clock you could share? I'm seriously considering mocking one up just for the cool factor... It'd be nice to get it at least approximately the right size. (I'm also considering building a working model Globus indicator too. Maybe I'll just size everything based on the most suitable globe I can find...)
