This is the Forgeworld Command Rhino. This model is from the Golden Demon Display Cabinets at GamesDay 2005.
It won the Forgeworld prize in the Golden Demons. The radar dish actually randomly rotated.
The painter did a lovely paint job. Inside were flashing lights, you can see a red LED in the following photograph.
In my opinion this should have won the Gold Golden Demon for Warhammer 40K vehicles.
Just look at the detail and superb paint job. Certainly an inspiration for me.
