For sale is the Stern factory NY Public Library and Mattel modified containment unit. Both were removed from my GB Pro prior to upgrading to the Premium. No permanent modification is required, both are easily removable and use existing mounting hardware. Will include paper print out of shrubs if you decide to cover Sigourney's head to make it look more like the premium. Minor screwdriver ability required, no soldering or anything too technical.
