It looks like this is a system using a tube as a plate, I'll have to look it up to see if it was coated after casting or if they just applied the design straight onto the zinc. It would probably be set up by laying out transfers just as a stone would be.
It also sounds similar to the press Brett Litho had.

This is way over my head Steve this is mentioned in the patent but I'm not sure if it's for what you're referring to.
Edited to add I could be wrong but the way I read it American Lithograph bought the patent so they may have been the only ones using this type of press for years later.
