For those who are so inclined, spray painting the cameras are easy. I have 4 V2’s painted a satin black, including a portion of the power cords.
I set the camera’s backside down on 1.5" ± tall pedestals made of cut, folded and taped cardboard.
The masks for the lens and sound openings were 1.25" diameter fender washers with the holes covered with pieces of tape. The washers were centered in the main black disk with just a fringe of black showing around the edge of the masking washers. The small black disc below the lens can be painted over as it is only cosmetic.
The cameras were painted in the collapsed state. Later tilting of the cameras was accomplished with beveled styrofoam painted black. The masking washers stayed in place by there own weight.
They came out very nice.
P.S. The styrofoam angling wedges were later replaced with folded sheet metal wire protection plates, painted black. Because they are steel the cameras magnetic base adheres to them very well.
