I was just wondering if anyone out there has seen one of these before, or knows anything about it or the company that made it. I know it is an automatic boring and facing head but what makes it odd is that it has a miniature light bulb built into the case, I was just curious what this would be for. I have taken the item apart and a small battery is inside, the on and off switch has some type of linkage connected to the diameter setting dial. The battery has corroded but I think I can replace it with a newer style. The coarse adjustment dial gives 0.001 inch per increment and the large top ring gives 0.0001 inch per increment. Please let me know what you think. James
