Not only does it slide fore and aft, but the table also slides in and out.
I believe the entire assembly was made in house by Country Coach as it is part of the cabinet/table casework. It should be able to be duplicated if you can get access to a coach to take all the necessary measurements and then have a capable custom cabinet shop make it.
As I recall, the tables CC mounted directly to the wall did not have this fore and aft, in out feature. Only the ones with the "buffet" type cabinet.
