Fantastic job on the restoration. I love how it still shows it's age on the top face of the rails. Amazing.
I don't have much on this company, but I do have ads dating from between 1871 and 1901, showing locations in New York and Cincinnati.
I have not been able to confirm they are the same company as the "American Billiard Table Co. Jersey City, NJ". I don' know if they are the same company and had multiple locations (same way that Brunswick did) or if they moved, or if they are different companies all together.
Either way, hopefully this helps you in your search, and hopefully you'll share whatever else you find with us here.
