If Steve want's to confirm it, I believe I'm one of the few with the oldest SD Stutio Obi EPIV saber he made. I got this from him about 12 or 13 years ago. There was no actual graflex clamp on it. The look of the clamp was simulated. And no transistors, no ring of holes in the emitter, no "windvien" viens. The entire piece is machined metal with exception to the "gear" and clamp lever which are both cast resin. I've toyed with the idea of selling it. Although I'm not sre how much this would be worth.
