Maybe you could research it and let us know what you find out. It might be possible to track down the patent, or, I was recently informed, the Soviets kept everything they captured and the Russians still have it somewhere. You could try and get access to whatever they have on Siebel?sgeorges4 said:that all we get about this project?
