Will Mercedes Branded Cargo Box Fit T-Slot in Aftermarket Roof Rack Crossbars

Question:

I picked up this cargo box very inexpensively at a garage sale. However, Im trying to figure out what type of crossbars it needs. It looks to be a Mercedes OEM. I didnt see an exact model. It looks like it has a T connector, but also a second slot, which is confusing me. Do you have any idea what this might be? It looks a lot like a Thule 1200. Sorry for the bad quality pictures. Anyway, any advice would be appreciated on what crossbars I should try. Would a regular T rack work using only the single T bolt?

It doesn't look like any Thule box that I have ever seen but we rarely get a look at the ones they make for dealerships. If there is a part number on it anywhere you may be able to call a Mercedes dealer and have them look it up.

I can determine if it will fit an an aftermarket set of crossbars if you can tell me the length, width, and height of that rectangular block that fits into the T-slot. the second slot I think you are talking about may just be to adjust the box to be either more forward or rearward on the crossbars.
