"Com Ser Laboratories BR-1000 Service Monitor". For parts only since this unit is so rare that one would have to possess it already to have a shot at a restoration. Information is hard to find but I believe that this company was the previous "Lampkin Laboratories" and this might have been their last product. I would say that there is some interest in this unit from folk who have oneMissing is the top oscilloscope unit. I have included a photo of what one would look like if complete. I do not have a complete unit, though; the last photo I included in this auction I found online. Although not stated explicitly before, this one does not power on.
