Clearly an oddball turntable. Dual 1229 question.

I picked up a dual 1229 turntable today which in itself isn't too odd but the case is. The turntable is set in a smoke grey acrylic, lucite or plexiglass case. Both the top and bottom are see thru. Basically I'd like to know if Dual sold them like this or maybe this was a special display model. It doesn't look aftermarket to me. It looks like the turntable came this way from Dual. Thanks
