I very much doubt Chester would tell you.

Most of these machines, especially from the bigger suppliers, all have slight variations. I know a couple years ago I looked at something G0704 like, and out of all the different machines around that size I looked at (around 8 to 10 IIRC), they all had slightly different specs. Some were obvious things like different spindles, and others were more subtle like axis having slightly different amounts of travel.
