I am not an expert, but I thought there was only one Festool router table, OK two between the VL (attaches to MFT/3) and GE (free standing), both currently available, but an older model..? Did you get a part number or pictures perhaps?
Maybe I'm wrong. Just have seen it at two different Festool Dealers at a discount. Since they are only allowed to discount discontinued part numbers I've assumed it is an older version.
Before the CMS there was the Basis system which took different modules. It was based on the MFT1080 extrusions and doesn't have the V groove on top and is a different height to the MFT/3.
The basis system acceptes all of the CMS modules plus it has a few for the old, now superceeded, saws.
It can take the CMS-OF for the router but not any of the sliding or extension tables.
I use mine attached to an MFT1080 with an Incra fence mounted on the 1080 whenever I get really sick of the Festool fences lack of easy adjustability and slopiness.
