Tom,<br><br>Thank you very much for all of the information, and for your personal story. It's a very, very good story. I was fascinated. You may want to look into writing before you settle down on a career. :-)<br><br>Incidentally, I'm not so sure that we can use the gun or the cartridge. It sounds awfully proprietary. We'll see. We'll make sure we have the right one of our own to put our name on. <br><br>Yours,<br><br>John
