Thanks. I didn’t know they used that devise. Makes more sense now.

Their kinda clunky number system got blown away by the sheer rapidity and scale of Roman expansion, so, for example the "i" representing ones would be used ahead of "million" for various things, like wheat units shipped.

Looked interesting so I did a little digging and found the set here...

Please note - I kept getting a “The connection was reset” message from Cyberfox but Chrome let me download the .pdf with no problems.

http://www.opensourcemachinetools.org looks like an interesting site.

Fascinating designs, huh? Most all of that mechanical motion control is now handled via digital electronics. All of that will be (or already is) lost art.
